I tried all the Babolat damps, Sampras O Ring, all Wilson damps, Technifiber, Gamma, and several others. They all took away too much feel and made my racquet feel utterly stiff, with the exception of the Wilson Smiley. It had a good blend of dampening and retaining feel. However, lately I've been addicted to the PURE feel; no dampener. If I feel the ball on the strings, I can determine whether I'm hitting properly or in need of adjustment. This can help me be more consistent. Volleys on my KBT are nice and crisp, but its a heavenly sensation without any damps muting the feel and sound.
