I use tourna grip over the leather grip using grup size 4 1/4. However, most of the rackets I found are in 4 3/8. I need to take-off the leather grip, and want to replace it with a synthetic one. What is the recommended replacement grip? My hand is very slippery, and so far only Tourna grip & yonex supergrab works well. I have broken several rackets in the past, as it slips from me during my first serve. I hold a friend's racket with Head hydro control. I like the feel, almost as soft as leather. How is it in the "absorption" performance?
