I have 3 head racquets, play a bunch, and didn't think my grips had suffered much since I always keep fresh over-grips on them. Then, I bought a 4th racquet and realized just how much I had compressed the stock grips. So.... I was looking to just buy 4 new grips and replace them all. Unfortunately, the choices are staggering. Any suggestions? Only thing that sticks in my mind is a demo I did a few months back. It was a Head racquet with a black Wilson grip (and no over-grip). I could really hold the racquet well -- but I worry about the summer months and lots of sweating. Any suggestions are most welcomed.
