Going from a strangley shaped Pro-Kennex Composite Dominator, to a Pro- Kennex Composite Destiny, allowed my game to progress rapidly, when I was in my late 20's, because of a much better balanced and consistant head size, of 95", if I remember correctly. That frame mold design was later sold to Babolat, to make their first racquets and looks a lot like the Are-Pro does today!
I wish I still had that one!
But the racquet that make the BIGGEST change of all, was a Wilson K-Factor Bold, that I bought last May, that brought me back into the game, after over 20 years away from participating in it!
For $35 on the bay, it felt like it was made for me, when I first tired hitting a tennis ball again.
