Hey guys, I'm a 4.5 player and I've been playing tennis for about 8 years now. I'm currently using the Wilson six-one tour 90 in 4 1/2 and have been for the past 5 years or so. I'm considering moving down to 4 3/8 and was wondering if anyone else has done this and can offer some insight. Did you like it more? What were the effects on your balls from going down to a smaller grip? Do you like it better? Did you go back to 4 1/2? If you could also include your ntrp that'd be great! Thanks guys!
