Thank you for listening to the Racquet Quest Podcast!

I am posting here to make an addition and a correction to a previous podcast, and this is quicker than waiting for a week or so for a new episode.

The “Stringing and Racquet Data” podcast was cut short, so I will finish it here. 

We were talking about the three (3) scale system we use to determine the torsional balance. The racquet is weighed at the midpoint of the head at the “top” and “down,” and the butt cap is resting on the third scale, and that is called the “butt.”

I don’t recall the podcast numbers right off, so I will use numbers from another racquet to explain. The racquet is a Wilson Ultra 100. The “top” weight is 95.3 grams, the “down” weight is 96.0 grams, and the “butt” is 119.9 grams for a total of 311.2 grams (10.97 oz.). So you can see the difference between the “top” and “down” number is only .7 grams, which is about a quarter of the weight of a vibration damper!

However, if this number was over 5 grams, we may want to “match” the numbers a little more closely! But, what if we wanted to increase the “top” weight by a lot to have the head heavier on one side than the other side? Why? Maybe a “training” aid to remind the player to keep the head lower, for example. Our experience shows that a difference between the “top” and “down” of 6 grams is noticeable.

On the Yonex VCore Pro 97 – Racquet Review, I noticed after the fact that I had indicated the Ereca System calculated the balance (CG) to within one-tenth of a centimeter! That would be pretty good, but in fact, the Ereca System calculates to within a tenth of a millimeter! Very precise! As of now, the Ereca System does not calculate swing weight as I tried to correct on the podcast but wanted to confirm that point.
