Gamma Supreme Power Tennis Overgrip

this is the best grip I've used yet. It costs a little more than the regular overgrips, but is worth it. the grooves allow me to hold the racquet handle even looser so i get more snap out of each stroke. My only complaint (aside from the the cost) is the asymmetry. The grooves fall/start on different points on either side of the racquet.

I have tried many others overgrip and I chose this one because it is so comfortable and keep my grip tightly to volley or hit the balls I is also absorb the hand's moisture well while playing during hot Summer temperature.
