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 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

Model Comparison

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

Now for some fun!

Play Like a Girl…Part Deux

If you read “Play Like a Girl,” you will have a good idea where this is headed!  This part is intended to make it possible for you to experiment without feeling “forced” so it is based on “numbers” not “feelings.”  Of course, feel is relevant to tennis players.

Two events this week make it easy to compare numbers and feeling.

  1.  A racquet came in from a tournament playing junior that had the good fortune of picking up a competitors racquet and recognize the difference immediately and wanted to try it.  His racquet is a Babolat Pure Strike 16×19 with a swing weight of 302!  The racquet he picked up has a swing weight of 341!  His revised swing weight is 325.
  2. A really good young lady is switching racquets and string setup, so there is a four (4) inch strip of 1/4″ tape on the inside of each side of the string bed in the 3 and nine o’clock position — total weight of about 5 grams, for a swing weight of 321.  During a training session, a coach said the racquet was too heavy and removed about 2 inches total of tape, maybe 1.5 grams, and everything was fine!  This player is strong enough to play with a 335 swing weight so was this a “visual” suggestion, and the process of removing tape convinced the payer that the racquet was now much lighter?

In case you don’t remember there are 28.35 grams per ounce.  So you can see that 1.5 grams is quite small!

Did you know that a dry overgrip is about 5 grams and a wet over grip can be as much as 12 grams?  The location of an overgrip (under your hand) has virtually no effect on swing weight so it generally goes unnoticed.

Unless agreed upon in advance most weight can be removed or re-located so don’t fear your friend…weight!

 

Digital Ball Pick Up!

Nope, this is not a smartphone app!  This is even better!

This digital pick up system is designed to prevent premature aging and premature bumper guard destruction!

Here’s the deal…we see way too many tennis racquets that have been rendered nearly useless because the protective bumper guard, that plastic thing that fits over the top portion of the racquet, has been totally ground away by scooping the ball up with the top of the racquet then placing the ball against your foot and dragging the ball up your leg!

A client was in yesterday with two (2) used racquets that were for sale.  At first glance racquet #, 1 looked OK but with the typical “ball scooping”

Worn Out Bumper Guard

abrasions on the top.  A quick probe did not reveal a hole in the graphite fiber so a new bumper guard would be a “cosmetic” necessity.

Racquet #2 did have a new bumper guard which was a “red flag” of sorts.  We removed the new bumper guard which exposed significant damage to the racquet to the extent that the graphite fiber was completely worn away!  Obviously, this racquet was not worth much.

The digital system eliminates this destruction of the bumper guard and benefits your flexibility.

Here goes:  when standing in front of a ball bend at the waist a little and bend the knees enough to reach the ball.  Now with the thumb and first two digits (first and second finger) grab the ball and pick it up!

What could be easier!

If you are holding a racquet you can place quite a few balls on the string bed and carry them to the ball hopper!

If you are thinking about telling your racquet technician this destruction is due to your “aggressive playing style”, forget it.  Just start using the “digital ball pick up system” so you will not be faced with this embarrassing question.

String Bed Stiffness – A Short Video

It is raining today and it felt like a good time to talk about “string bed stiffness”…so let’s go!

This quick video will make a plea to you tennis players to demand more from your racquet technician so you are getting the most from your equipment.

Thank you for watching!
