My overgrip of choice right now is white Yonex Supergrap and I wouldn't consider changing but I've read that the product has recently changed much like the Wilson Pro changed a while back. I have tried Gamma Supreme which is very tacky and I don't sweat a lot but I sweat enough that I don't feel confident in my grip with Supreme because it is so slick. I don't like Tournagrip at all. The Supergrap absorbs enough for me right now because I still have the old version (about 13 or so left I think). Anyways I was looking into the Tourna Tac but I thought the Volkl Supergrip II sounded good but there really aren't too many posts about it from the searches I have done. So I was wondering if some of you use Supergrip II and how it compares to Supergrap, especially for sweat absorbtion. And opinions of Tournatac are welcome as well.
