Hi, Here in Indonesia, they only sell 3/8 grip size, and I have to use Wilson Micro Dry Replacement Grip on top of every racket I have so that I can have the right grip size for my rackets. My questions are, whats the thickness of the micro Dry replacement grip or any replacement grip in general? Few days ago I just purchased head fxp prestige in TW with 1/2 grip size, should I use the wilson replacement grip again or enough with just an overgrip? Or i should just get the 5/8 next time? thanks.
