I know there are several on this board who play with a leather grip and without any overgrip. Do you buy the same size racquet as you would if you were using a synthetic grip? I normally use a size 3 (with synthetic grip) and use a tournagrip to achieve my ideal size. However, I recently got a PS 6.0 95 (with Fairway leather grip) and found the grip to be much too small. I want to play it without an overgrip so I think I'll have to buy a size 4. Do you guys also buy a size up from your standard size?
