I normally use leather grips underneath an overgrip because of the great feel you get compared to a synthetic grip. I tossed my racquet today and tore the bottom of my overgrip so I took it off but we were only playing for 10 more minutes so I just used the bare leather grip. Wow, I loved it. It was hard, but never felt uncomfortable at all. I got great feel and just felt like I was hitting slightly better. I am going to try it out tomorrow but for the whole hitting session and see if I have any problems with it. BTW it is a babolat leather grip. Anyone use just a leather grip still?
