I have used Gamma tennis grip with the raised rib for a few years. Very good grip. I just ordered the Klipper grip and put it on a racquet and it feels as good as the Gamma grip. I'll see how it holds up and send in a 2nd review.
Positive Ribbed Black Racquet Grip
I've used these grips for more years than I can remember. They are cushioned and provide a good feeling in my hand. Easy to wrap and cost effective!
have been using this grip for years and never disappointed with the feel and performance.
