No sponge rubbers

I am using a Dawai 388C-1 pimple rubber with no sponge.Whats the difference of having a sponge and not? I find it difficult to block and play backhand shots from this rubber.When I block, the ball usually dips down to the net or go out of the table.What should I do?

Hi Praveen,

The sponge under the rubber gives you more control of the ball.  Without sponge the ball stays on the bat for a shorter time so makes it harder for you to control where the ball is going.

Since you are having trouble with controlling it I would change to a rubber with some sponge.
