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!

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.

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.

 

 

 

 

 

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 Lite

As you probably guessed, this is the lightest of the Speed Series, 100 square inch head size, at a weight of 281 grams (9.91 ounces)!

There are several positive features in this racquet and one is the reasonable flex (stiffness) of 63 RDC, plus the uniform string pattern that provides a consistent hitting experience needed by developing players.  This pattern should contribute to extended string life as well.

Head Graphene 360+ Speed Lite

As with all light racquets, this one can be customized as the need or desire arises, and I think that will happen more quickly than most other racquets.

This is just too light, in my opinion, for players wanting to improve all aspects of their game.  Remember, weight is your friend!  However, if you prefer a light racquet for any reason this is a top choice!
