Sponge has a great influence on the effectiveness of table tennis playing. It determines the speed of the ball and increases its spin.
Based on the leading manufacturers’ experience, the VT developers managed to create a special high-energy sponge which can give a ball maximum speed-up. It is highly homogeneous, light and very bouncy. Moreover, energy sponge gives good sense of control in any game situations.
Due to this kind of sponge the spin and speed indexes were improved considerably (for about 35%). This is why you will win steadily playing table tennis with a VT racket.
