Leaded or Non-Leaded?

This used to be a decision you made when putting gasoline in your car, but, not so much anymore.  It is, however, a decision you make when it comes to racquet performance. For this discussion “lead” means “weight”.  There are, of course, other types of weight. Racquet performance can be enhanced with the proper placement [see more]

Tolerance. What is it?

When we think of “tolerance” we think of traffic, noise, and generally putting up with things, but normally we don’t think of tennis racquets! However, we should!  Tolerance means “what is the allowable variation between racquets of the same model”.  Not all racquet manufacturers are the same but it would be a good guess the [see more]

Ereca Visits Florida!

Eric Ferrazzi of Ereca France has been in Florida for several days but not just for the sunshine! Eric is spending a lot of time working on diagnostic equipment designs. I have dozens of racquets that can be tested, re-tested, cut, and everything in between so a good sampling of data can be taken on [see more]

Worst Grip Size Reduction, Ever!

I know none of you would do this, but someone did and probably charged real money for it! Naturally, the client wants it fixed, but how, without spending another $100.00 or so. The first problem is that the butt cap was not removed before the reduction began.  You can see the pallet is no longer flat [see more]

Pro Stock Racquets. Really?

We devote a great deal of time to understanding racquets and what makes them ”tick”. Of course, it is fun and meaningful but sometimes not well understood. Hardly a week goes by that I don’t have a request for “Pro Stock” racquets of some sort. But what does that mean? To help sort out this [see more]

IART Resources

I want to compliment IART on being a wonderful resource of knowledge. I recently had a question regarding one of the training seminars I attended at the 2015 Symposium. Thanks to Tim helping me contact the seminar leader directly, my question was answered immediately. Plus I had a most enjoyable conversation about racquet customization beyond [see more]

What Difference Does it Make!

I was preparing some new racquets for extension today which normally goes without an issue and today was no exception but one racquet had a “shot” of silicone and the others did not. It is simply a procedure that manufactures use to  make the static balance the same on all the racquets of a particular [see more]

Rossignol Swingtest

Many of you may remember back in the day, before the Babolat RDC, before the Prince PTC, the Alpha Accuswing or the Gamma RTC there was a company that made a very nice compact swing test unit. The company was Rossignol and they also made racquets that were used by some notable players like Mats [see more]

My Time with the Alpha Accuswing2

I have been using the Alpha Accuswing2 every day for well over a year so it is about time to evaluate the performance of this device. The Alpha Accuswing2 does one thing and does it well.  The Accuswing2 does “swing weight” period!  That is a good thing since it can be sold for a reasonable [see more]

Special Customizing Class at 2014 Symposium

For all who have attended the symposium and gone through the racquet customization class with John Gugel, you already know what a great class it is. There are a lot of people out there who can string a racquet but there are not that many who are really good when it comes to knowing all [see more]
