Hard and soft rubbers

Hi I'm Ali

What's the difference between hard and soft rubbers?

For example Sriver and Sriver FX.

Hi Ali,

The soft rubbers allow the ball to sink into the rubber a little more and is easier to generate some spin. The harder rubbers allow you to brush the ball because the sponge doesn't allow the rubber to wrap around the ball.  It is a different feeling for both and they require different strokes to generate the spin.
