Unfortunately the original grip on my SW37 was the worst grip I've ever had on a racket. It really slipped up and down on the wood. Putting an overgrip made it worse, because the overgrip slided WITH the original grip. That was pretty annoying. No I have a Karakal replacement grip on the racket -> Much better. Superb hold and feel. Actually without an overgrip. But honestly, it's too small (G2). On the other hand the thin grip makes the racket head heavier - a welcome side effect, especially if you've got a 4U racket.
