All of us are going through a very trying time and eliminating as much exposure as possible right now will bring a quicker end to this virus!

Please be safe!

Racquet & Tournament Management

Management is not just for adults!  Juniors that play tournaments need to have some management skills!  During this coronavirus slow down it is a good time to learn some of these management skills.

We see many different management slip-ups such as no racquets for the tournament tomorrow!  All racquets have broken string and are at the bottom of a bag nobody wants to stick their hand into!

Juniors Management Tip #1:

Every Monday takes every racquet out of the bag.  If one or more are broken leave them out of the bag.

Juniors Management Tip #2

To get some idea of how much longer the string may last simply try to move the 5th or 6th cross string by pulling up toward the top of the racquet. If you can not pull the cross string up it is time for stringing.  If you are able to pull a cross string up pay attention to the “snap” it makes as you push it back into location.  A serious “snap” indicates a deep notch.

Monofilament strings typically fail by notching which makes it difficult to move the cross strings.  If your string is a multi-filament and looks like the picture on the left it is time to string!

Abrasion Fail Visual Test

Notching Visual Fail Test

What if neither of these conditions exists?

Every racquet in your bag should have a tag indicating when the racquet was last strung and if it has been more than one month it is time to string, period!

Just for fun you can go to our SFC function and get a good ideas as to how many times per year yu need to have your racquet strung.

Head Graphene 360+ Speed PWR

I suppose you have a pretty good idea what PWR means, right?  Well, you would be correct!  The Head Graphene 360+ Speed PWR is just that at a calculated power value of 2297.5!  Compare that to the calculated power value for the Head Graphene 360+ Speed Lite of 1838.3!  Twenty percent (20%) more powerful than the Lite!

This is what a 115 square inch head size can do for a racquet!  The strings are quite a bit longer and more widely spaced which contributes to power, and comfort.

This head size is normally referred to as a “game improvement” racquet and relegated to those players that were not too athletic and/or didn’t want to exert too much energy on each stroke.  In other words slow and short swings.

I am not sure that is the case with this racquet!  Sure it has a big head and a thick beam but it sure does feel good when picked up (first moment)!

If we were going to recommend this racquet I would suggest some weight added to the rear end.  The head does not need any additional weight.

Head Graphene 360+ Speed MP Lite

The Head Graphene 360+ Speed MP Lite may be the perfect racquet for a player looking for a thin(er) beam, 100 square inch head size, slightly lighter than most MP racquets!

As you will see in the specifications this racquet is about 28 grams (1 ounce) lighter than the MP model, and, just a little more flexible, or better said, less stiff!

Forty-nine point nine percent (49.9%) of the total weight resides toward the head of this racquet, so if you think in terms of “points” it is 0.16 points head light.

Some customization will make this a racquet that you can stay with for a long time. As your skills advance, so can the racquet!

Head Graphene 360+ Speed Series Comparison

Head has included six (6) racquets in the new Graphene 360+ Speeds series!  It is important, I think, to know what the difference is, and, it is not always easy to compare racquets.

So, here is a comparison spreadsheet and graph that will give you an overview of the entire lineup.  I have included “string bed stiffness (green)” because it shows just how influential “inplane stiffness” and string spacing is.

This is real data based on racquets that are now our “demo” racquets.  No modifications have been made and no advertising was considered in these specifications.

Head Graphene 360+ Speed Series Comparison

Head Graphene 360+ Speed S

I think we all know what “Pro and MP” mean but what about “S”?  I am not sure, so we are going to call it “Special”!

The Speed S is indeed special and probably one of the best all-around racquets for 2020!  You will see by the specs why this may be the case but a couple of things stand out.  A 100 square inch head size.  A uniform 16×19 string pattern and 25mm beam producing the stiffness of RDC 64!

The overall weight and swing weight are just right for most advancing players and can be modified when the need arises!  This is really a “players” racquet in disguise!

Head Graphene 360+ Speed Pro

This is the “PRO est” of the new Speed series because it says so right on the tip of the racquet and it carries an 18×20 string pattern, so there!

However, do not be intimidated by the “Pro” label!  You will see by the specifications that this is a racquet that can be used by any player wanting to maximize their current skillset.

A couple of good reasons for this assessment is the wonderful flex of RDC 60!  The overall weight and swing weight are there as a good beginning but can be adjusted to suit any player.

Typically 18×20 string patterns are not considered spin-friendly but the dense pattern can be used to your advantage by reducing string bed stiffness, thus dwell time and therefore spin potential.  In other words, this pattern is highly customizable!

Head Graphene 360+ Speed Pro

If you value string life the 18×20 pattern can reward you with some increased durability.

As we mentioned in the Graphene 360+ Speed MP review there didn’t need to be many changes from the previous version and probably the most noticeable change is going to be the color “flipping” and a little increase in swing weight.

The numbers will tell the story.  Click here to see the Graphene 360 Speed Pro data from last year.

Head Graphene 360+ Speed Mid Plus

The new(est) model of the very popular Graphene 360+ Speed series racquet is available NOW, so get up to “speed” by taking a look at the specifications for a strung racquet and the series comparison data.

The major difference between this and the previous version is the “flipping” of the colors! What was black is now white and what was white is now black! I believe not very much else was changed and for good reason! The racquet is a very, very good racquet so why make a bunch of changes? I don’t think Head made a bunch of changes!

Here is an overview of all the new Speed models. This is unstrung data, however, you can add 16 to the overall weight for string and 30 to the swing weight number to approximate the strung data.

By The Numbers

Here we go with this numbers thing, again! 

Our Racquet reviews are a bunch of numbers, but what do these numbers mean to you?

We have put together this table with a brief explanation of how each number can be used by you to understand how that property can be helpful.

If you see terms such as typical or normal, ignore them! With tennis players, there is no such thing as “typical and normal”!

If you need to be convinced, take a look at a previous post!

Please let us know if there is a number that needs more clarification or a number we are missing!

Head Graphene 360+ Prestige Mid

The Head Prestige Mid is, in my view, the quintessential Prestige! This Prestige is the tennis racquet you would buy even if you don’t play tennis! It would sit right next to your Porsche 550 that you don’t drive much, but both make you feel really good!

The latest edition of the Prestige Mid is the Graphene 360+ Prestige Mid, and it carries on the iconic tradition of all previous models and looks better doing it, in my opinion.

In left image, you can see the overall color scheme of all of the new Prestige series, but you can’t see the detail of the “cap system” that is different than the other three (3) Prestige models.

The lower image shows the transition location.  But why?

Mid Cap System Transition

 

 

 

I think it is just a matter of weight. The cap system on the Mid stops halfway down the head instead of all around as on other models.

This slight reduction in weight allows for more customization options and this is a very customizable racquet.
So, if you are interested in an “iconic” racquet to place next to your 550, this is the one!

What could be better than arriving at the courts in your 550 and pull out your Prestige Mid racquet!

Game, Set, Match!

Head Graphene 360+ Prestige Pro

So, what’s in a name?  In the case of the name “Pro” it is weight!  Right out of the box this racquet is ready to go with a wonderful weight and swing weight that you will see in the specifications.

The Prestige Pro is the “different” Prestige in the series with a more sculpted geometry.  This is most noticeable in the shaft right above the grip with tapers and contours all the way to the throat.  The head geometry is more elliptical in cross section than the flat section used in other Prestige racquets.

As you look at other Prestige racquets the difference in the cross section is noticable.  The Tour for example has a “flat” beam cross section and the shaft right above the grip is also a “flat” cross section with little very little “sculpting

The Prestige Pro is a racquet anyone can use with a nice 16 x 19 string pattern and reasonable stiffness.

This is a legitimate 95 square inch racquet with a 16 x 19 string pattern that suits most players.  The full Prestige “cap system” adds a nice measure of stability along with swing weight that gets this racquet into the “power and control” category.

Head Graphene 360+ Prestige Tour

When we do the testing and “number taking” for our demo racquets, we try to think as the consumer may think and include comments that may help the consumer make the best decision.

We do not want to make these posts so dull that you go to sleep, but data is essential, so we are going to include it…so stay awake!

Data is particularly relevant to the Prestige Series from Head.

This review is for the Prestige Tour, and it points to the differences between Prestige racquets that may go unnoticed or misunderstood.

The Prestige Tour is a 99 (645 cm²)square inch racquet with an 18 x 19 string pattern. If you have read the post on the Prestige MP, you may wonder, what’s the difference?

You may notice that the Prestige Tour has one (1) fewer cross string. Not a big deal. You may see that the Prestige Tour has one (1) square inch larger head size. Also, not a big deal. What you may not notice is the Prestige Tour has an in-plane stiffness of 400, and the Prestige MP has an in-plane stiffness of 359. That is a big deal! Even with a bigger head and fewer strings, the Prestige Tour has a higher string bed stiffness than the Prestige MP. The higher the in-plane stiffness, the less the racquet will “bend” during impact.

The Prestige Tour is more stiff overall (62 v 58) than the Prestige MP, and the 21.5mm beam contributes to that stiffness.

So, take a look at the numbers for this racquet to see if you can find other exciting differences!

Head Graphene 360+ Prestige MP

We are finally getting the time to work on these marvelous new racquets from Head! In this case, it is the Head Graphene 360+ Prestige MP.

The Prestige is a fascinating series for Head, but I think it is often overlooked when considering a new racquet purchase. I believe the “performance” category excludes a lot of players that could very well use this racquet if it is appropriately set up. Secondly, I think players have the mistaken feeling that the Prestige series is too stiff!

I believe you will see by the following specifications that neither are necessarily true!

The Prestige series is, in my opinion, the best looking new racquet in a long time. However, in a performance racquet, what does “looks” have to do with it? In my opinion, a lot!

This racquet is the “true” 98 square inch (630 cm²) head size with an 18 x 20 string pattern and, of course, the excellent “cap system” that contributes to the performance of this racquet. You will see in the specifications that the swing weight is on the “light” side, allowing for customization to suit any player.

Head is now including a CPI, “Control Power Index,” and this racquet ranks as a CPI 200 compared to the Prestige Pro at CPI 300. The difference is a function of the tight string pattern and flex. The thin 20mm beam throughout contributes to the nice flex of RDC 58 after stringing.

A lower CPI indicates to us that the racquet will do no more than you ask of it! If you want the ball to go fast you swing harder! The racquet will not force to to “fear” your stroke!

If you are considering an 18 x 20 string pattern this racquet should be right at the top of the list.

Our COF numbers are quite good which indicate a positive contribution to “spin” considering the tight string pattern.

Grip Shape and Size Customization!

Racquet Quest, LLC is really happy to announce an addition to our Grip Shape and Customization capabilities!  After several years of design and experimentation we have 3D printed grip pallets!  Our grip pallets are printed locally so your racquet stays at the World Headquarters!

Custom Printed Grip Pallets

Due to the racquet manufacturing variations it is not feasible to print a “bunch” of size 3 pallets, for example, so we design and print a grip pallet for your racquet exclusively!

So, if you want your racquet to have a “rounder” grip shape, or a “flatter” grip shape it is possible!  In fact if a grip of an unusual shape is required, and the racquet shaft is compatible, that can be produced!

Extending a racquet is now more efficient due to the length of the printed components.

If a full blown extension is not part of the plan right now a “finishing plug” with the desired length is designed and printed to fit your exact shaft dimensions.

Please contact us if you have questions about the process, and what dynamic changes will occur, and what additional customization might be desired.

Due to the “customization” that may be required on the racquet the manufacturers warranty, if any, will, most likely, be “voided!”

 

Yonex VCore Pro 97 HD

Have you ever wanted to play with a Yonex Pro racquet but really want a 18 x 20 string pattern?  Well your want’s have come true!  The new Yonex VCore Pro 97 HD is that racquet and it is here!

The great new green and gold cosmetic creates a “menacing” tool for your game.  This is a “thin” beam racquet measuring 20.0mm through out the length which results in a flexible racquet.  That flex combined with the “mesh” material in the grip area should make this a comfortable hit with just enough feed-back to be helpful.

The 18 x 20 string pattern, thus the “HD” designation, makes this a control oriented racquet allowing for massive strokes for increased ball rotation.  The “HD” should contribute to extended string durability but if this raacquet suits your playing style string durability is not top on list of considerations!

Yonex says “For advanced players looking to play aggressively with added precision, feel, and stability”.

Other VCore Pro 97 racquets wil be here soon but in the meantime take a look at the specifications of the VCore Pro 97 HD.

Brittany Tagliareni: Person…Tennis Player…Friend

We hope you will enjoy this video that was aired recently on The Tennis Channel!

We have been working with Brittany and her Mother, Cathy for several years and they have been the most wonderfuly enlighting years!

What Brittany allowed us to do was try to configure the racquet, grip and string setup that would provide the best tactile feedback and consistency.  Brittany is currently using a Yonex SV100 and Ashaway MonoGut ZX string.

If you don’t already know Brittany the following video will get you accquainted.

Head Speed 10th Anniversary Edition

The new Head Speed 10th Anniversary Edition is here and whether you are a collector or serious player, or both, you need to see this model!

The all black, with some gold splashes, racquet is here in the MP and S versions, and both the same specs as the non anniversary edition which, by the way, has put a Head racquet in the top five best sellers in the US!

Typical of all Head Special Editions and Anniversary Models this racquet comes pre-strung with another set of string attached for those that don’t like the current string setup.  A good move, in my opnion.

These racquets are here now so  stop by and take a look at this beaitiful Anniversary Edition.

A Picture is Worth a Thousand Words!

In this particular instance, a few words are required to make the picture make more sense.

Thanks to Australian stringer Ashley Nugent, for asking, is the picture in the post “Is Your Racquet Healthy” accurate in terms of failure?

It is highly unlikely that a main and cross string will break at the same time in the same location.

The image was taken a couple of years ago and had to do with “elongation” not the failure and, I grabbed it to show what I mean by “obvious” in the subject post.

I am pretty sure the cross string in the picture was “cut” to illustrate the difference in elongation not string failure.

Thank you, Ashley!

Is Your Racquet Healthy?

I started thinking about this as I made my way to a routine doctor’s appointment last week. Here is the scenario I formed while waiting:

The doctor has been seeing all sorts of patients already today and I suspect the first glance at each one elicited some sort of reaction, quielty probably, like this; “Good Greif, that guy is fat! Bad trousers, terrible shoes, nice shirt, whats with the hair, dude?” etc, etc.

So what do you think happens when a racquet shows up for a checkup?

“Good grief, that is an old racquet, who would ever buy one of those, this person is too good for that racquet,” etc, etc.

As humans we can communicate how we feel to the doctor but your racquet can not, so it has other ways to tell you if it is healthy or not. Here are a few signs of an unhealthy racquet:

  1. Grommet set, and specifically the protective head bumper is worn out. If this is not fixed quicky the racquet will die!

    Worn Out Bumper Guard

  2.  Grommet set individual barrels are broken or missing. If this is not fixed the strings will die!
  3.  Overgrip is disgustingly dirty requiring exam gloves to remove it! Doctors use exam gloves too and you know what that means!
  4. Under grip is essentially rendered to powder, requiring exam gloves to remove it.
That is a real image!  It is obvious that a new overgrip is needed.

Obvious!

What is not so obvious sometimes is that strings need to be replaced.  Even before they break!  What!

Yes, strings loose tension over time and in some case rather quickly!  By knowing what the original string bed stiffness was we can determine how much “stiffness” has been lost.  For most players a degradation of 20% is maximum.

Depending on the string material a loss of 8 to 9% overnight is not uncommon…so that leaves 11 to 12% for playing.

Take a look at our String Frequency Calculator to get a better idea of stringing frequency required to keep your racquet really working for you.

To keep you playing at your best you need to keep your racquet at it’s best!

 

 

 

How to Demo a Racquet

We have what seems to be a zillion demo racquets, and there is a player for each of them, I suppose.

One of the biggest complaints against “demoing” is precisely that…too many to choose from!

This is what we recommend;

  • Start the convesation with yourself before you need to make a decision.  Allow a month before the “season” starts if you can,and start the conversation with us early on.
  • What do you want that your current racquet is not providing.
  • What is your budget.  If you are a junior what is your “sponsors” budget.
    • With these three questions you are well on the way to a painless “demoing” expreience!

Here is what we would like to have to speed up the process:

  • Bring your current racquet in “play ready condition” with you to the primary discussion.
  • Tell us what has changed physically since you selected the current racquet.
    • Injuries, including tennis elbow, shoulder and wrist issues, or a long layoff, etc.
  • What do you want the new racquet to do that the current racquet is not?
    • Power, or “POP”, Control, Comfort, Grip Size, String Issues, etc.
  • Do you have a brand preference?
  • If we can make your current racquet better will you not demo other racquets?
    • It is possible that the current racquet can be better than it is so demo it as well after some customization.
    • Tell us if this is of interest or “I want a new racquet…period!

With this information we can make the demoing process much more fun,consise, and ultimatley rewarding, and in a much shorter time period.

Our demo process is free however we believe the racquet should be “setup” just as it will be used which may require stringing and a litttle customization and there will be a charge for that if you agree.

Our huge database of racquet specifications allow a quick look at the characteristics you prefer.

We think you wil be surprised at how much fun the demo process can be!

 

 

 

Head Graphene 360 + Gravity Lite

If you guessed the Lite is the lightest model in the Gravity series you are correct, but did you guess  it is also a 104 square inch head?  Two 104 models in the series!  I say “way to go”!

Model Comparison

Head Graphene 360 + Gravity Lite

The 16 x 20 string pattern remains but the spacing is slightly more “open” than the “S”.  The “Lite” is slightly stiffer than the “S” therefore a slightly higher power calculation you will see in the specifications.

The “Lite” can be the perfect racquet for those looking for a 10 ounce racquet, and whose game is “settled in” and are not looking to make a bunch of stroke/technique changes!

The “Lite” will come in the smallest grip size of any Gravity model which is important when fitting a smallish person with a performance racquet!

Head Graphene 360 + Gravity Pro

The Gravity Pro is the racquet all 18×20 players have been waiting for!

Why? Great weight, and excellent swing weight right out of the box!  For players that think the Prestige models are too stiff, (they are not), this model will provide feed-back that the Prestige damps out through the cap system.

Big hitters will benefit from the 18 x 20 string pattern when going for the “flat, down the line” shot.

You will see all the specifications later on but now let’s talk about the reaction to the binary graphics package that is used on all the Gravity models. One side is Lava, and the other side is Miami Green ( my description) which makes for an exciting pickup reaction!

Head Graphene 360 + Gravity Pro

The excellent stiffness of RDC 60 combines with the dense string pattern to yield an effective stiffness of 30.7.

Head Graphene 360 + Gravity MP

The new Head Gravity MP seemed like the perfect place to start with this new series of racquets so that is what we did!

We believe this racquet falls between the Prestige and Radical series and will appeal to more players than either of those.  Plus, there are two (2) 104 square inch models, the Lite, and S.  These are relativley “thin” beam, (Lite and S = 24.4mm) racquets that Head has been missing, in my opinion, for a while.

It has a “flip” color scheme…one side is lava and the other is Miami Green (my word).

IMG_0396

Head Graphene 360 + Gravity MP Lava Side

The head shape is a little more round.  The weight is 312 grams (11.01 oz) which I think is a little light.  The swing weight is 324 kg/cm² ( a good starting point).

The unique fiber layup is designed to “uncoil” at impact contributing to a new kind of power, and hopefully comfort.

The Series consists of a “Pro”, “MP”. “MP Lite”, “S”,  and”Lite”.  There is a Model Comparison post where you can see all of the racquets in one place.

Head Graphene 360 + Gravity Series Lineup

In addition to individual model specifications we like to do a consolidated series comparison so we can glance at the differences between racquets.  Following is that comparison.  All the data is taken with strung racquets with a vibration damper but no overgrip.

See the Five Models Compared Here

See Larger Images of Each Model Here

So, what is important in this data?  Well, to us, everything or we wouldn’t include it but we like to explain some of the not so obvious numbers.

End Weight:  the weight of the butt end of the racquet when using two (2) electronic scales

Tip Weight:  the weight of the top end of the racquet when usisng two (2) electronic scales

Why important:  this accurately calculates static balance and allows easy maching of multiple racquets

Swing Weight:  the higher the swing weight the higher the energy colliding with the ball.

Why important: this is the most meaningful number in terms of momentum into the ball.

InPlane Stiffness:  this tell us how stiff the racquet is when a load is apllied to the 3 and 9 o’clock positions.

Why important:  a higher number means the racquet is stiff in that direction affecting string bed stiffness.

Stability:      this tell us how the racquet reacts to ball impact.

Why important:  the higher the number the more power and control that can be contributed to the racquet.

Position 1, 2, and 3: three (3) electronic scales are used to weigh the racquet.

Why important: we can match the rotational inertia of each racquet.

Peak Load:   this tells us the peak force of the ball impact on your body.  Higher loads contribute to injury.

Why important:  we can make adjustments to the string bed stiffness to keep the peak loads safe.

Everything else should be clear but if you have questions please “Ask John”

New Head Graphene 360 Radical! Here Now!

The new Head Graphene 360 Radical has arrived and I have already chosen the one for me!

The four (4) racquets in this series cover every possible player style and the new graphics package will appeal to most players.  This is a win-win Radical Series!

Head Graphene 360 Radical Series

Just in case you are wondering which one I have chosen it is the Radical S!   Why?  I handle a lot of racquets each day and this racquet just “feels” good when I pick it up!  Plus the 102 square inch head size fits me fine.

This series is the most impressive Radical Series I have seen in a few years.

You can read the reviews of each of these racquets on this site but you really should come by and take a look and “feel” for yourself.

My setup is going to be this racquet strung with PEEK at 52 pounds.  I am going to increase the weight to 315 grams and the swing weight to 315 kg/cm² as well.

I am anxious to start playing again and this is just the racquet to motivate me!   Motivate yourself, too!  Get one!

This is a comparison sheet of the four (4) models so you can get some idea as to which racquet may suit you!

The Rebel Backpack and Radical 6 Racquet Combi add to the excitment of the new Radical racquets!  Complete the package with these bags!

Head Radical for 2019!

The new Head Graphene 360 Radical series continues the “less is more” graphic package that is so popular on the Head Speed series. While I really like the occasional “Limited Edition” racquets I am favoring the new “look” now.

Head Graphene 360 Radical Series

As you can see there are four (4) models in the series starting on the left with the “Pro”, “MidPlus”, “S”, and “Power” versions. The obvious concept here is the minimization of graphics, however, not so obvious is the subtle color changes inside the head of the racquet.

I have compiled unstrung specifications which are important but not as much fun as racquet to racquet comparison which I will do between this series and the series of last year.

Unstrung Specifications

If you are interested in “approximate” strung specifications add 17 grams to the “overall weight” and 30 grams to “swing weight”.

So, until then enjoy the new Radical look!

I will be posting full reviews of each model by the end of the week so check back…and you can stop by the World Headquarters to examine these racquets yourself!

Now You Think of it!

So, it has been a while since you had your racquet strung and you are standing on the court about to receive and you ask yourself; “I wonder when I should get my racquet strung”.

Now is probably not the best time to think of it but if you do simply take a look at the short video for a quick answer;

Accuracy Index…what is it?

For a few years, Racquet Quest has been using an “accuracy index” to clarify and understand how the string bed stiffness at a given location can affect where the ball goes. You may say that is the players skill working…or not!

However, players take heart, we know how the string bed accuracy can and will put the ball where you didn’t intend for it to go!

Our Accuracy Index is predicated on racquet support effectiveness and main and cross string junctions matching the “target tensions”. The natural ratio of the racquet is the basis for the target tensions. The “natural ratio” of a racquet is the difference in main string tension and cross string tension in a freshly strung racquet. For example; the main string tension is 50 and the cross string tension is 38 the “natural ratio” is 76%.

The Efficiency Index is the measure of the stringing machines support capabilities. The lower the number the worse the machine support is, therefore the racquet is under a lot of stress and we know what stress does to everything! It is bad!

What Took You so Long?

A lot of players don’t really know how long it takes to string a tennis racquet. Do you?

This is not a quiz but a way to begin the discussion of why it may take us longer to do your tennis racquet and why we may not be able to accommodate certain time requirements. Speed does not take the place of “doing it right”.

What Took You so Long? Doing it Right, that’s what! The entire process!

Putting string in your racquet is part science, part art, part craft, and part habit. What Racquet Quest tries do do is minimize the “habit” part because some habits are awful! I have been presenting at various seminars for over twenty (20) years and I have seen most of the bad habits but they change with the introduction of new tennis racquets and/or tennis string.

I have been testing potential stringers for the USRSA CRT and MRT certification for many years so I get to see every stage of stringer development. But this post is not about that…

What Took You so Long?

Let’s start with the string. Every string we install is first pre-stretched in it’s entire length, about 40 feet. This procedure increases the stability of the string so tension loss is mitigated somewhat. In some materials this will also increase elongation and elasticity. Every string gets this!

Total Time: 3 minutes

Our proprietary software, Racquet Record, keeps data of every racquet we do so we can pull up the last stringing and activate it for the new stringing that is about to take place. If the string is not broken we take current SBS readings to determine stiffness loss over time based on the previous SBS data.

If the racquet is used, and currently strung, a careful examination is performed before the string is removed. The string is removed in a specific pattern to minimize stress on the racquet. The racquet is then cleaned with an effective but harmless chemical and blown “dry” with also removes any grit that may be in a grommet barrel.

Total Time: 5 minutes

Now the racquet can be mounted on the stringing machine, which you will see in the video. By design our machines require additional setup time to assure the supports are properly adjusted. To the casual observer it looks like this will take “forever”… it does not, and it is critical to the stringing result.

True Tension Professional Machine

Friction is the enemy of a good stringing result so the string holes are aligned with the tension head and with the guide post every string is pulled almost friction free. You will see this in action in the video.

When installing the cross strings a series of string spreaders are used to provide a friction free weaving of the cross string. Does this add a minute or two to the process? Sure, but it is worth it and every racquet we do gets it!

Total Time: 25 minutes Watch the video here

About 25 minutes after the beginning of this process the racquet is ready to come off the machine. Because the racquet did not distort the removal is easy and without stress on the racquet.

After the racquet is strung (the next video) the data acquisition phase begins. This is absolutely essential to player and racquet performance! Almost every property of the racquet is reduced to a “number” so if something needs attention we can associate a number to that property and make the necessary adjustment(s).

Total Time: 15 minutes Watch the video here

Thank you for taking the time to view this post. We hope you enjoyed it and now have a better understanding of what we do!

Our Standard Stringing Process

After seeing “After the String is Strung” some of you wanted to see a “While the String is Being Strung” video.  I have several videos of the stringing process but I use them for my own review and to see if there is anything that can be done better.

So, the video(s) will not be “professional” videos and are intended for fun and maybe some understanding of what we do.

Grab a coffee, or something, and enjoy 24 minutes of stringing fun!

Wilson Clash Tour

If you read the Wilson Clash 100 review there is not much to say about the Wilson Clash Tour in terms of graphics because it is exactly the same!

So we can go directly to the differences between the two models. The Tour does have the “word” tour on the racquet but little else in terms of racquet specifications and that is by design.

Wilson Clash Tour

Typically a racquet will have some little tiny descriptions such as weight, head size, string pattern, etc. but these racquets have none of that. Wilson, with this racquet, wants the player to make all the decisions based on “feel, control, and power” and not be influenced by descriptors. As you might expect this model is a little heavier overall and in swing weight thus the “Tour” designation.

Our Wilson Clash and Clash Tour demo racquets are strung with Luxilon Natural Gut as the main string and Wilson Sensation Plus as the cross string. This combination should maximize the performance of the racquet.

Before we get to the specifications of the Tour model there is another slightly unusual design feature. The grip pallet is not molded onto the frame but is formed by the carbon fiber. This manufacturing technique does not allow for easy (seriously not easy) grip size and shape customization so be certain you get the grip size you need.

Take a look at the following data to see if you think this new concept is worth a try. Based on the feedback we are getting I would say yes, definatley!

Unravellin​g Athena

Brittany Tagliareni brought this film to my attention a couple of years ago and I have tried to follow the progress since then.

Here is the latest trailer for the film…

Wilson Clash 100

Once in a while words “fit”! Clash fits this new Wilson racquet because it disrupts the trend of “everything stiff”. Luckily this trend is dying and Wilson has, in my view, done a masterful job of expediting that demise with this concept.

Wilson Clash 100

Not only does this racquet look good it just feels good in the hand. It is light, maybe too light, but the brain detects something different about this racquet. We all know racquets are all about “the brain”!

In this review you may notice the addition of a couple of specifications. One is “Racquet – In Plane Stiffness”. This is the racquets resistance to”squeezing the sides together. The higher the number the more resistant (stiffer) the racquet is. Another addition to the review is the three (3) weights taken at the sides of the head and at the very bottom (butt cap) of the racquet. This very helpful when matching or customizing a racquet. so I thought we would include it.

Before this racquet is strung it has a noticeable “softness” which is expected given the 52 stiffness (Wilson is not using the defacto device, RDC, for their stiffness rating). However, after stringing, the racquet takes on a different “feel”. It is like the string is pulling all the material components together! I intend to hit with this racquet tomorrow so as right now I have no idea how it will feel.

To get the maximum from this racquet our demo is strung with Luxilon Natural Gut, 125 and the new Wilson Sensation Plus multi-filament with a “wear” wrap. This should be a great setup, so if you want to hit with the latest technology this is it!

For each racquet we do an “Accuracy Index”. This tells us how accurately the ball will come off the string bed when hit at different locations on the string bed. This racquet has an index of 97, which is very good, in the areas of the string bed that show the most failure (breakage). The overall string bed index of 94 is quite good and tells us that the string bed should produce as much accuracy as the players skill allows!

Take look at the following specifications to see if you agree with the player evaluations you may have read.

What is Elongation?

In dictionary terms it is:

“the amount of extension of an object under stress.”

In tennis terms, it means the same thing when talking about tennis racquet strings.

How much does a string stretch under the reference tension load or otherwise stretched (impact)?  The proliferation of wrist, arm and shoulder injury has brought attention to the property of “stiffness.”  The problem is that your stiffness may be different than my stiffness, so there needs to be an “index” associated with each string, in my opinion.  I have that data on over 500 tennis strings, but that is just me.

The images show the results of high elongation (left) and low elongation (right) string upon breaking.

Several years ago a player asked me “where is the string that is missing?”  Well, it is not missing.  The ends you see should be connected!

If the string has little elongation when it breaks there is nothing “pulling” it apart like the high elongation string. So each time you hit the ball, the string either elongates a bunch or it doesn’t.

In the case of the high elongation string, on the left, it absorbs a good portion of the “shock” associated with a hard hit, whereas the low elongation string, on the right, lets your body do the absorbing to a great extent.

So, it is reasonable to use very low reference tensions for low elongation string (35 to 45 pounds; 16 to 20.5 Kg) and higher tensions (45 to 60 pounds; 20.5 to 27.2 Kg) for high elongation strings.

You may ask, “how do I know how stiff a string is?”  If you see the word “polyester or co-polyester” it is likely that string wil be stiff compared to natural gut, most nylon based multi-filament construction, and PEEK (Zyex) material.  In my opinion, there is no “bad” string just “bad” applications.  If in doubt…ask!

Does String Color Matter?

Recently a friend asked “would the same string but different color play differently”?

Of course the only way to confirm anything in terms of “playabilty” is to prepare a racquet with both strings, lab test them then hit with them. We will try to do this soon.

That is the next step but what about the strings themselves?

Our typical testing provides the following information. You may click on the first slide to see this in a “slide” presentation format…

Carbon Mapping…GPS for Your Ball!

Wilson has introduced a new generation of tennis racquets that do not include GPS but maybe something just as good!

The new Clash tennis racquet is what I am talking about! This new racquet will be in the shop on February 15 and wants to say “hello”!

What makes this such a different racquet is the ability to “adjust” stiffness to the players swing. I have not done a complete evaluation of the racquets so it is premature to go into detail, however, I have felt, and measured the stiffness in the lab. There is a considerable softness!

But where does the GPS thing come in? So, the material layup has been designed to combat the lack of control of very soft racquets, therefore, when you smack the ball the racquet will become stiffer, ergo, control is enhanced and the ball should land at your desired destination! Just like GPS, right?

From the beginning, It has been the mission of Racquet Quest to minimize the “injury” potential of stiff racquets combined with stiff string. We believe this racquet is a step in the right direction!

The Clash racquet comes in two (2) models:

Wilson Clash

Clash 100 & Clash 100 Tour

The only difference is the weight. The string pattern is 16×19 and slightly “open” for better ball capture.

These racquets are available for pre-order now. We have a limited number arriving on or about February 15 so place your order soon.

I will post more specification details when the racquets arrive so the data is lab “tested” so check back in mid February, or stop by and see the racquets and say “hello”!

Instinct…get it!

The new Head Graphene 360 Instincts are in the shop waiting for your evaluation!


As you can see this new Instinct Series carries forward the “minimalist” graphics concept and a stunning blue color!  

If you have been shopping for a new Porsche lately you may have seen a similiar color they describe as “Miami Blue”!

The Instinct Series offers a MP, S, Lite, and PWR (Power) models. And, thankfully, and amazingly, these performance racquets are realistically priced!

I will be adding racquet specifications soon so come back or sign up for notifications so you won’t miss anything!

All Instinct models are at the Racquet Quest World Headquarters so stop by and take a look.

Weight is Your Friend!

Is this instance we are talking about racquet weight. Not the few pounds we put on yesterday, Thanksgiving Day!

In the early 1990’s we made a tennis racquet which weighed slightly over 7 ounces.  Awesome, some said!  This racquet traveled along with the standard weight racquets in the line and was available for anyone to hit with.

“Hit” in this case is a misnomer because the mass of the racquet was not enough to get the ball over the net in most cases!  Instead of a “hit” it was like a light “shove”!

With out a doubt the weight of a racquet must be “usable”.  Take a look at these brief warm-up videos to see weight in action then we will find out how much these racquets weigh and the swing weight…

Sophie Hitting

This is a Wilson Blade 98 18×20 pattern.  Racquet weight is  329 grams (11.61 Oz.) with a swing weight of 332 kg/cm^2.

Next let’s take a look at a different player…

Aleks (aka GBS) Hitting

This is a Head Radical with the Pro Cap System creating a racquet that weighs 340 grams (11.99 ounces) with a swing weight of 349 kg/cm^2.

It is obvious that both payers are swinging the racquet with gusto and it should be obvious that the racquets are stable on impact and this stability is necessary for power and control.

So the next time your oppponent asks if you have “gained weight” it will because the ball is coming at them with more “heaviness”!  And you can repsond “yes!” with a smile on your face!  Just like Robert, Sophie, and Aleks!

Head Graphene 360 Extreme

If you can’t get by Racquet Quest to take a look at this exciting new racquet just take a look at this video!

The specifications will be posted here as soon as possible, but in the meantime…

You Have Been Waiting for These!

You may not know it but you have been waiting for these!

Head continues with thier anniversary edition parade!  It seems twenty-five years is a good time to re-introduce the racquet(s) that made history then!

Head Radical 107

Head Radical 98 Limited Edition

The Head Radical 107 OS is a remake of the Andre Agassi racquet that is true to the characteristics of the era!   Great weight, perfect flex, workable swingweight, a 18×19 string pattern, a 107 square inch head, and minimal graphics!  This may be the purest example of a remake I have ever seen.  It even comes with the rubber band vibration dampers Andre used!

The Head Radical 98 MP is the newer racquet geometry and 98 head size.   The graphics reach back twenty-five years for the colors but the design is definately contemporary.  Plus, this racquet accepts the  Head Pro Player Cap System grommet set.  Yes, that means you can turn this Radical into a “beast” just like the previous versions!

I will be posting all the specifications of both of these as soon as possible but they are in the shop so please come by and take a look, and feel, for yourself.  These are limited edition racquets.

A New Logo!

After all these years of the old “RQ” it is time for a new look!

Please ket us know if you like the new look!

Head Graphene 360 Speed Pro

Head has introduced their new Speed Series, and it is here, yes, I men here, with some significant changes!

The most obvious and dramatic is the move toward a minimalist “look.”  The graphics consist of black and white!  Gone are the days of multi-colored Speed racquets.

As with many Head racquets, the graphics mimic the “SkiTip” angle as seen with the logo and white paint headed in the same angle.

Less obvious but no less important is the “360” designation that has replaced the “Touch” designation that was on the last series.

Players of the Speed series don’t want muted, as suggested by “Touch” they want feedback!

And, “360” suggests the use of Graphene in more areas of the racquet.

This image is the Graphene 360 Speed Pro, a highly maneuverable, flexible, (57RDC) racquet with an 18×20 string pattern.  This may be the ticket for juniors that can’t handle a heavier, stiffer racquet but need the dense string pattern to mitigate string breakage. I would not recommend any stiff string in this racquet, however.

I am a little surprised by the low swing weight (306kg/cm2) but this can be increased as necessary.

Jack Anthrop Scores Big in Nassau!

Congratulations to Jack for his Finalist finish in the Junkanoo Bowl in Nassau!

Jack has been playing ITF events and was a qualifier for this tournament.  Not only did he qualify, Jack went on the finals where he put in a great three (3) set effort against Harrison Gold, 6-7,6-2,5-7!

Jack Anthrop & Harrison Gold
Junkanoo Bowl

Well done, Jack!  Congratulations

Meet Jennifer

Jennifer walked into the World Headquarters of Racquet Quest the other day and asked to have her racquets strung.  Nothing unusual about that, of course.

I looked a the racquets in her hand and thought to myself…” Well, where are they?”

In her hands were two (2) Head You Tek IG Prestige Mid racquets!  If you don’t remember these, they are the pinnacle of the Head Performace series racquets.  The head size is 93 square inches; the weight is 350 grams (12.35 ounces), with a swing weight of 309 kg/cm2 (10.9 ounces), and a racquet flex of 64 RDC units.

This is a great racquet for sure, but I don’t see many anymore in the good condition as these are.  One needed a grommet set, but that was all.

The reason I mention this is to reassure tennis players that they are capable of using racquets they normally scoff at including a comment “I am not good enough to use that!”   A lot depends on what you want to do with the racquet.  In Jennifer’s case, she wants to get to the net as quickly as possible, and the nice recoil weight of 146.1 makes this a good racquet at the net!  The low swing weight enhances the “mobility” of the racquet which also means this is not a particularly “powerful” racquet.

The new Head Graphene Touch Prestige Mid is still 93 square inches but now has a 16×19 string pattern.

If you are interested in hitting with a Head Graphene Touch Prestige Mid, our demo is strung with Babolat VS Touch natural gut which represents the purest combination I can think of!

Thank you, Jennifer, for giving me an example of what tennis players are capable of!

 

Big Bag Blowout…Again!

This seems to be a semi-annual event but that’s OK!

This event is a little different though!

Every bag regardless of size is only $60.00!  This is extraordinary but we need the room.

Most bags are Head or Wilson, some are 6 racquet bags some are 12 racquet bags.  It makes no difference!

Walk in with three (3) 20’s and walk out with a bag worth twice that much!

Hurry because this event is for in-stock bags only and the supply while taking up a lot of room, is limited!

This picture is not representative of all the bags.  Call for a quick update on available bags!

What is “Best Overall Performance”?

In our “Recommended Stringing Frequency” calculator we state that this frequency is to get the best possible performance from your racquet.   But, what exactly is “best performance”?

To establish this we need to take you, the player, out of the picture for a moment and concentrate on the racquet and string setup.  the reason is simple:  no two players strike the ball the same way.

We start with “Swing Weight” which is the most important dynamic property of a racquet.  So a higher swing weight will contribute to power and stability, thus performance.

Overall weight is important because you need to be able to get the racquet to the court and out of your bag!  Heavier racquets contribute to energy, stability, and comfort.

Effective Stiffness is important because it represents the stiffness of the string bed (SBS) and the racquet stiffness (xxRA, or something like that).  This number represents the impact each time you strike the ball.  The higher the number, the stiffer, of course.

Of the four (4) things mentioned above we can control the string bed stiffness with ease.  One of the easiest methods is to string your racquet regularly to maintain the effectiveness of the elongation of the string being used.  Elongation relates to energy return in a string and while strings will stay resilient for a long time a well-worn string takes a while to return energy to the ball.

You, the player, of course, determine performance so when using the SFR you can enter a high UTR or Style rating or a low UTR or style rating if maximum performance is not required.

New Head MXG 1

Head is introducing two (2) new racquets to the MXG Series, and this is an excellent thing in my opinion!  It is not that we need a bunch of new racquets, but this signals a commitment to the MXG concept.

In case you don’t know, the MXG Series racquets incorporate a “string suspension system” (my words) into the throat of the racquet.  The most notable of this system is the bright silver paint. However, the most important function(s) is the increase in main string length across the entire throat area and torsional stiffness for control.  We now have ten (10) main strings that are the same length in the throat, and this does contribute to “power.”

The Head MXG 1 is a 98 square inch head with a thin beam (22mm) that puts it in the “player” category, but it may need additional weight for big hitters.  You will see all the specifications below.  If you are a player and have shied away from the MXG for head size reasons, this is for you!

Head MXG 1

The MXG 1 demo is available now.  Call to reserve it!

The new MXG 1 is available for pre-order and will available May 11, 2018.

After the String is Strung!

I have often wondered what players know about the “stringing” process and in particular what goes on after the “string is strung”.  So, while Madelyn was here she decided to video me doing what we do after each racquet is strung and just coming off the machine.

Had I known we were going to do this I might have dressed up a little, emptied the trash and fixed the crack in the wall behind the RDC!  But I didn’t.

This video is offered as a “real-time” view of what we do with every racquet and is intended for information and fun only.  If you have any questions please let us know…now enjoy the movie!

Congratulations Sophie!

A huge congratulations go out to Sophie Williams for her terrific run at the recent Easter Bowl in Indian Wells, Ca.!

Sophie played the finals against the number 3 seed Elena Yu…

Having the experience of making the Girls’ 12s final last year, Eleana Yu of Mason, Ohio, said she only had to fight a moderate case of nerves as the No. 3 seed won the Girls’ 14s USTA gold ball and her first Adidas Easter Bowl national title with a 6-1, 6-0 win over No. 7-seeded Sophia Williams of Charleston, S.C.

“Having been in the final before really did help,” said the 13-year-old Yu. “I did feel a little nervous at the start, but once I found my rhythm it was fine and I just felt really confident. I think my opponent was more nervous, but the match was definitely closer than the score indicated.”

Sophie’s great result at the Easter Bowl continues her recent extraordinary results at tournaments around the country.  Below is Sophie holding the first place trophy of a previous tournament.

Sophie, the Winner!

Sophie, the Winner, again!

 

If you have been to Racquet Quest in the past several years, you have probably seen some of Sophie’s forty-five (45) racquets either in “process” or being prepared to ship to her.  Sophie is left-handed, so all the leather grips and overgrip is wrapped left-handed, and each racquet is “sequenced”.  All of the racquets are “matched.” so the only thing that is different is the string bed stiffness (SBS).

Even racquets that are done on the same day may have slightly different string bed stiffness numbers due to the time between racquet number one and racquet number eight.  Sequencing indicates in what order the racquets can be used.

That may seem like a lot of racquets, but if you play as many tournaments as Sophie you need a few!

When Sophie is in town, she is either at the USTA Center or training with Robert Kendrick at the Winter Park Racquet Club.

Congratulations, Sophie!

 

 

Mr. Dailey Makes a Visit!

The Racquet Quest World Headquarters had the pleasure of having Curt Dailey, CEO of LaserFibre Strings, visit today!

Racquet Quest, LLC will be doing a little evaluation work on LaserFibre string made in the United States!  LaserFibre is the only string supplier committed to making all of their string products in the United States.  Right now this is not the case, but they are headed in that direction.

Curt has been in the tennis business for many years and is trying hard to bring updated string products to the market.

Welcome to Racquet Quest, Curt!

 

What Keeps Us Going?

Have you ever wondered what keeps the Racquet Quest World Headquarters going? I can’t imagine why you would, but here it is anyway!

IMG_4065

Power!

These are made in France, of course, so they are good for you, and after work, they pair up nicely with a good Bordeaux!

 

And Now This…

In the words of Lord Kelvin (May 1883) “When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts advanced to the stage of science.”

That is why every racquet we do has over fifty (50) numbers attached to the finished data. Most of these numbers will remain unknown to the client, but for us, it is imperative that we know them.

Numbers Matter!

Which leads me, again, to this very important discussion.

Every day we see a statement from tennis string manufactures claiming, or suggesting, their string is the “softest ever tested” and other claims.  What the heck is “soft” anyway?  There is a lot more to it than meets the eye so we have done significant analysis on bunches of string and can now quantify “soft” as it relates to tennis string.

What is “soft”?
In 1994 I did a presentation for the USRSA in Atlanta. What was the topic?

“Understanding String.”

It is now 2016, and we are still trying to understand string! Especially “soft” polyester based string.

In 1994 PolyStar was the only polyester based string I was familiar with. Since then there are dozens of offerings from anyone that can afford to purchase from manufacturers and market the string. If you have a desire to do it, I applaud you!

In 1989 I started testing string and calculating “power potential.” Why “power potential”? Because “modulus,” “elongation” and “elasticity” didn’t get to the bottom line of string performance quickly enough! The steps to arrive at power potential are many.

For the testing, several calculations take place including “stretching” the string as in a ball impact. The difference between the first calculation and the “stretched” calculation is the power potential!

I have calculated hundreds of power potentials but have not until now quantified “soft.”

I think now is the time!

Under the direction of Dr. Rich Zarda, we have done a tremendous amount of work on this issue so we can now distill this work into the following explanation.

So, what is a “soft” tennis string?

Strings in a tennis racquet carry the ball impact load in two ways:
1) Via the pre-load string tension placed in the strings caused by a stringing machine (and the racquet frame “holding” those tensions in place) and
2) Via additional tensions that develop in the same string caused by the elongation of the strings as they deflect with ball impact.

Both of these conditions occur simultaneously and contribute to the string bed stiffness (SBS, units of lbs./in). Racquet technicians measure SBS by applying a load to the center of a supported string bed and measuring the resulting deflection. Dividing the load by the deflection provides the SBS (lbs./in). The lower the SBS, the more power you have (power here is the ability of the ball to easily rebound from the string bed), but the less control (presumably); the higher the SBS, the less power you have but, the more control you have (presumably).

One more point about SBS: the lower the SBS, the less the load your body will feel for a given swing. But for an SBS too low (less than 50-80 lbs./in), balls will be flying off your racquet going over the fence; and for an SBS too high (greater than 200-240 lbs./in), the racquet will hit like a board with significantly less ball rebound. So the most common SBSs are between 100-200 lbs./in: a balance between control and power.

As already expressed, SBS is a function of the pulled string tension and the string elongation. Here is what is interesting: For large string elongations (for example, greater than 15%) and reasonably pulled string tensions (greater than 30-40 lbs.), SBS only depends on the pulled string tension, and it does not depend on string elongation. Additionally, for this condition, SBS, for these high elongation strings, does not change as a ball is hit with more impact.

linearity_noname

But for a string bed with low elongation strings (less than 5%) under low pulled tensions (less than 20 lbs., or tensions that have been reduced due to racquet deformation and/or string tension relaxing with time), the SBS additionally depends on the string elongation and will significantly increase, in a nonlinear ever-increasing way, for harder ball impacts.

In order to achieve a repetitive feel for a player when hitting with a racquet, it is best to have an SBS that is independent of an increasing ball impact force. This will lead to a more consistent playability of the racquet, which includes a more repetitive feel. This desired “feel” implies using high elongation strings (greater than 10%). If low elongation strings are used (less than 4%), the SBS will significantly increase as the ball impact force increases, resulting in a racquet feeling “boardy” for higher impact loads. And low elongation strings will cause un-proportionally increasing load into the body.

deflections

As you can see by the graph, elongation contributes to SBS in a big way. The red line indicates a stiff string, about 4%, and the blue line indicates a “soft” string, about 15% elongation. You can see the loads increase dramatically as the impact increases. So the harder the hit the higher the loads on the body.

So to the question asked at the start “What is a soft tennis string?” In the context of the SBS discussed above, I would suggest that a soft tennis string is one whose elongation is 10-15%, and a stiff tennis string is 4-6%. And any string under 4% should be categorized as ultra-stiff.

String elongation (soft, stiff, ultra-stiff),  stringing machine strung tension, and string pattern(s) all contribute to SBS and SBS is an important measure of how a racquet plays and should be adjusted for an individual player, stiff and ultra-stiff strings can lead to less-repeatable racquet performance and player injury.

Soft = 10 -15% Elongation                Power Potential Range = 10.0 – 16.0
Stiff = 4 – 6% Elongation                   Power Potential Range = 4.0 – 7.0
Ultra Stiff =  Less than 4%               Power Potential Range = .65 – 3.96

 

Why Offer Racquets?

My answer is simple! To give you the very best performance you can get from your racquet dollar!

You are probably thinking “aren’t I getting that now from my online purchase?”

Probably not! I see a lot of racquets from online sources and what I see convinced me that you need to have another option!  The issues I see are typically poor string selection and really poor string installation.  String and stringing are very important, and you deserve better! We  offer racquets, in a limited sort of way, so you are getting what you expect!

How do I select what brands I will offer? Well, I review almost every racquet made either before or right after they are introduced and this review yields a great deal of information that is not normally known to the online consumer.

The Head Selection!

The Head Selection!

Wilson!

Some New Wilson’s

That is why you will see Head and Wilson racquets when you visit the World Headquarters of Racquet Quest. This selection does not mean other brands are not worthy of your consideration, and we are pleased to discuss all brands and offer them when appropriate.

Our racquet prices are attractive and the special service we offer adds to the value of your purchase.

Even if you just have a racquet question, we will be very pleased to help!

 

Monogut ZX = Zero Polyester

Ashaway MonoGut ZX Family

Image 7-18-16 at 2.20 PM

Ashaway, RI – “While it is certainly premature to proclaim the demise of polyester and co-polyester monofilament strings,” said Ashaway Vice President Steve Crandall in a newly published column, “I think it is certainly fair to say that the tide is against them, and that a counter trend towards “Zero Poly” monofilament strings is gaining momentum among tournament and other high-end players.”

In addition to growing complaints of arm pain and wrist pain and even injury, Crandall claims players are simply not reaping the benefits touted by the makers of these ultra-stiff high tech strings. “More and more high-end players are coming to realize they can get equal, if not better performance from newer zero poly monofilament alternatives, along with better feel, better playability, and reduced risk of injury,” he said.

In terms of spin generation, polyester’s main claim to fame, Crandall cited technical reports by Australian physicist Rod Cross and Tennis Warehouse University’s Lindsay Crawford, which demonstrate that topspin is generated not by the stiffness of a string material, but its ability to move laterally and snap back when striking the ball, characteristics shared by non-poly alternatives.

This is the case with Ashaway’s own MonoGut® ZX strings, Crandall claimed. “Here is a material that, 1) is nearly as slippery as polyester, and 2) has much better dynamic stiffness,” he said. “This means it can generate almost as much spin as poly, but with more power. Not to mention that it plays softer and offers much better feel. This is a combination people are beginning to notice.”

Crandall also cited comments by leading stringer John Gugel, who he quotes as saying, “To get the benefit of poly you have to hit the ball really hard. That’s when the string bed becomes non-linear and much stiffer. You can see it with professional players. They hit the ball just about as hard as they can every single time. And there are unintended consequences to that.”

Gugel said he, too, finds that players are increasingly looking for alternatives, and that they are very pleased with the performance of MonoGut ZX. “Most of the players that I introduce MZX to are a little bit skeptical of what it can do. However, after hitting with it, it is the consistency of string bed stiffness that they like. They find the spin as good as polyester and some find it better.”

Gugel said he actively discourages junior players from using polyester and that he has “a lot of juniors using 100% MZX and playing at a very high level.” Hybrid stringing is also a popular alternative, he added, with one of the best combinations being natural gut in the mains and MZX Pro in the cross strings.

Ashaway Racket Strings are made by Ashaway Line & Twine Mfg. Co., the only U.S. manufacturer of string for squash, tennis, racquetball, and badminton. Operated by the Crandall family since 1824, Ashaway has been making racquet strings since 1949, and is responsible for several important technical innovations. Ashaway has been the Official String of USA Racquetball for more than ten years, and is also the Official String of Professional Tennis Registry. Ashaway Line & Twine Mfg. Co. also makes braided products for medical and industrial applications. For more information visit http://www.ashawayusa.com. Zyex is a registered trademark of Zyex Ltd.

String Tension Testers…Friend or Foe?

The StringMeter is a device used to check the tension of an individual string. There are other versions of similar functionality, but this is what we use, and I will start with that.

Interestingly, this device traces its design to a tool that is used to check mainstay tension on a sailing vessel.

It is clear that our devices are well used, so they must be a “friend,” not a “foe”! And to that, I would say yes! The two (2) units shown here are “calibrated” units. One device is “free string,” and the other is “strung string.” These are different scales and very important for accurate information.

String Tension Tester

When we evaluate string or stringing machines, one of the most important values is the string tension with only the main strings installed. Using the “free string” scale, we check every main string and record the number.

Once the racquet is fully strung, we can check some center main strings and center cross strings with the “strung string” scale and see the variation. The difference between the two is the “natural ratio” of the racquet.

In addition to the stringing machine review use of the StringMeter, we also use it to calculate our “accuracy index.”

For this, we use the “strung string” scale and check each main string tension from left to right and every cross string tension from top to bottom and compare the actual numbers to the calculated numbers based on a non-distorted racquet. This spreadsheet shows how accurately the ball will come off of the racquet face.

The “efficiency index” tells us how much the racquet needs to change shape to reach that “index.”  

These are all essential functions of the StringMeter and String Tension Tester from Gamma Sports.

But, what if the StringMeter or other device is used without knowing what it is telling the user?

This is the “foe” part!

This would be the case if a customer with such a device has a racquet strung at say a reference tension of 55 pounds. The customer then uses the method to check the tension and finds that it is not 55 pounds or even close! The customer is not going to be happy!

If the customer knows what to do, they can check the main string tension as soon as they can after stringing, then, later on, to see how much the string has stretched without regard to the reference tension.

It is what it is!

When the racquet is no longer performing it would tell the customer how much the tension can deteriorate before stringing is required.

So, these devices are very useful for individual string tension but no so much for “string bed stiffness,” which is the total string bed as a ball impacts it.

We will look at some of the “string bed stiffness” devices in a future post.

 

 

I Get It! Maybe… or Maybe Not!

When we do a racquet review we try to deal with numbers!  Static and dynamic numbers to be precise.  We do this so each racquet can be referred to by properties and not just by subjective comments.  Make no mistake, subjective comments are good and can be used in fact to generate numbers!

Here is an explanation of the numbers and what they can mean to you.

It is well known that 5 players will have 5, or more, different “comments”, so having numbers provide a database, or history, of what works for what player style.  With that information, a new client can be playing with their “perfect” racquet is a very short time instead of trying a zillion different models.

This is important because players may not be using the best racquet for them because they rely on assumptions instead of numbers!  The very worst assumption is “I need a light racquet because I am just getting back in the game”.  The second worst assumption is “I need a big head with a big sweet spot because I am not very good”.  The third worst assumption is “I don’t need very good string because I am not very good”.

Bogus assumptions, every one of them!

As we look over our client data some things are clear and should become performance metrics;

  1. Total weight should be not less than 10.5 ounces (300 grams).
  2. Swing weight should not be less than 10.5 ounces (300 grams).
  3. Torsional stability should not be less than 15 units (typically grams).

With these metrics, you are off to a great start with a new racquet, or if you are beginning a new racquet search these numbers will be helpful.
