What do u perfer just the plain replacement grip or with overgrip on top/under watever ... I personnally perfer with out the overgrip cuz when i do it it looks uneven and its too thick for me ... thou im using one right now to cover the replacement grip is coming off at the top and i want to keep it down btw there arnt any shops that carry replace grips around so yea...
Usualy when you put the overgrip on top, make sure it's sort of taught so it would be even. Even if it isn't, over time it flattens itself out and you would not feel it. For the grip being too thick - do you mean the grip is too big? If so, it is probably because the handle size you choose was just right for you to begin with. What I do is get the right size grip, then choose the size smaller to factor in the overgrip and it works out. Typically you would want to use the stock grip and put an overgrip on top.
Well depends on youre preference, Im an ex tennis player so I like to play with medium sized grips XD
