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!

Year End

As this day nears the end and the year sprints to it’s conclusion it is worth the time to reflect on 2018!

This year was the busiest in the history of Racquet Quest, LLC and one of the most rewarding in terms of helping players.  Helping players is the “mission” of Racquet Quest so we appreciate the communication with clients that contribute to understanding the goal.

If you have been around Racquet Quest much you know the importance of discussions, some of which may be boring, redundant, or incredibly exciting.  It is the boring ones we want to eliminate.  We want every discussion to be exciting and helpful so beginning in 2019 we will be requesting comments, suggestions, and participation from you the readers of this and other posts.  Be assured that every comment will be treated with “care” and responses will be as meaningful as we can make them.

Racquet Quest, LLC World Headquarters

All of our clients are special and we thank each of them for letting us help their game.  Of course there are “Very Special” clients!

Brittany

Brittany Tagliareni is one very special player.  Brittany is Autistic and plays at a very high level in tournaments around the world.  I know you have read about Brittany on this site so we will not go into detail except to say Brittany has been an inspiration for me to become better in what I do each day.  Period!

We want everyone to be inspired and we hope it can lead to a healthier life and a better tennis game.  Please contrbute your inspirational story to our readers.  Here are just a few of the people that made 2018 so terrific…

Racquet Quest is looking forward to 2019 and we ask that you join us is making 2019 an incredible year for you and your tennis.

Thank you to everyone that made this year, 2018, a very special year!  I can’t wait to see what we can do in 2019!

How Lucky Can You Get!

Having one celebrity in the shop is quite rare but two…that is amazing!

The World Headquarters was visited by Bill and Aleks (aka GBS)!   What is also amazing is that they came in separate cars so they did have a choice!  If you are in the area stop by.  You may see a celabrity!  Probably not but you will see the latest racquets!

Visitors!

Brittany Tagliareni…a Winner!

In all the years I have been involved in tennis racquets I have worked with players of all levels, from top-ranked to no ranking at all!  The one thing that remains constant is that every player received the same attention to a goal.

Typically that goal is to win!

As I reflect on the high points of this journey there are a few players that really stand out. One of those players is Brittany Tagliareni.

  • Brittany is one of the best tennis players in the world.
  • Brittany has won many awards and accolades from the tennis community and press.
  • Brittany is Autistic.

Here is the deal. Every day I talk to players about the most minuscule of performance specifications…one (1) gram here, one gram there, one (1) pound here, and so on.

Brittany is different.

Brittany is very busy and wants to get to her next function whether it is taking care of dogs or tennis!  She really doens’t want to talk to me about tennis racquets!

So, to really understand what needs to be done her mother, Catherine, communicates for Brittany.

Brittany plays with a Yonex SV100 racquet strung with Ashaway Monogut ZX at 46 pounds.

She travels with three (3) matched racquets. This is where it gets interesting and one of the reasons I wanted to write this post.

Brittany needed some extra encouragement to hold the racquet with the proper grip (she is left-handed) to generate the amount of spin her coach wanted her to have. Just telling Brittany how to hold the racquet was not consistently working so we re-shaped the grip to offer some tactile “encouragement”.

The grip has been changed to have different “feelings” for each bevel of the grip shape. So one side is exaggerated for a certain length on the grip and other sides were accentuated shape wise.

The grip re-shaping had to be done in a laminated way because it works, is expedient, and minimizes costs associated with major grip modifications.

Now when Brittany holds the racquet she can feel exactly where it needs to be.

Brittany goes to Washington, and beyond!

See what Brittany has accomplished.

Brittany is incredibly busy so it is difficult to keep up with all of her travels.  Most recently she was in Dubai!

Turn the Head Radical Pro Into a Beast!

I am very happy to see players of every age returning to, or buying for the first time, racquets that have some weight!  Weight is your friend!  Any racquet can be “customized” to suit the needs of the player, of course.

But what do you do if you already own a Head Radical Pro?  You simply add the Head Players Cap System to your current Radical Pro.  This can be done the next time the racquet needs stringing and can be removed at the next stringing if wanted.

This is a “side by side” look at the Cap System Radical and the standard Radical.  You will need to like the color “orange”.

The Cap System can be added to many past Radical Pro racquets. The Cap System does not fit the Radical MP, unfortunately.

The image below shows the racquets and the specifications of each one.  You can see the difference between the two.  It is obvious that the major difference will be weight and swing weight.  The numbers between the two racquets are the data for the Radical Pro with the Cap System.

Turn the Head Radical into a Beast!

Brittany Goes to Washington!

Our good friend Brittany Tagliareni went to Washington recently and proceeded to win the Championship!  Brittany travels to play tennis and has worked her way to one of the top players in the world and has represented the USA at some events.

Congratulations, Brittany!

This is Important!

I was just going through some older posts and came across this “E” Book post and believe it is more relevant now that when I originally posted it!

Take a look because this is important!

What is Soft…er?

Head Visit

The World Headquarters of Racquet Quest was pleased to have Erika and Federic from Head visit recently. Erika is with Head in Phoenix and Frederic is from the Headquarters in Kennelbach, Austria.

Team Head player, Jack Anthrop was on hand to provide a players perspective.

Jack Anthrop

“Champion”

The purpose of the visit was to discuss a “grassroots” program that can effectively address, and contribute to the growth of tennis worldwide.

I was commenting on racquets and string selections, of course, when it dawned on me that Head has done an extraordinary job in designing racquets that have vast player appeal! A prime example is the Adaptive Series, introduced about a year ago, consisting of a “Speed” and  “Instinct” model.

Head Adaptive Length Extenders

This series can go from a lightweight standard length racquet to a more substantial, longer racquet in a few minutes! Plus this series can be either a 16 x 19 or a 16x 16 string pattern!

This concept is valid, and one that allows players to maximise the performance of the racquet. And the implementation is easy. Some changes can be made at courtside!

So, while I believe more can be done to get players into the correct racquet, the Head Adaptive Series is very close to being perfect!

New! Head Adaptive Tuning Models!

I have been working on these new models for a few days and will post more data as it is available but right now here a few points about this fascinating racquet concept.

dsc04103

The two (2) models are Speed Adaptive and Instinct Adaptive.  The racquets are both new versions of the current models with slightly newer graphics, that are, in my opinion very cool!  The Instinct has new graphics which will appeal to more players.

First, the Adaptive Tuning can create thirty-two (32) possible combinations, including increasing the overall length of the racquet.

The racquets are shipped in the lightest (285 gram), 16×19, 27.0-inch length format, and swing weight 287.

The Adaptive Tuning Kit is required and costs $29.00.   In the “kit” you will find a “heavy” butt cap insert, three (3) sets of grommet inserts to add weight and change string pattern, and three (3) sleeves that go onto the shaft to create length.

The length modification can be made quickly by the player, if necessary, however, the other modifications require the racquet to be unstrung.

These modifications should be left to your racquet technician.

Below is a spreadsheet representing the various combinations as they are applied.  This does not include all the options because the 16×16 grommet set did not participate in this session.

This was done at Racquet Quest, LLC and represents actual data, not calculated characteristics.
