Hi Amekun,

The thickness of the sponge determines the speed and spin.  The thicker sponge will make the rubber faster and also allow to generate more spin.

The harder the sponge is the less time the ball will stay on your rubber because the ball won't sink into the softer sponge.  This is a matter of preference for each player.
