? Optimal ball curve (OPTRA) / spin generation
? Power (SPI) / energy transfer
? Playing sensation (SPI) / controlMany years of development and researches were put at profit to conceive a revolutionary surface with a new rubber mixture allowing to further optimize the ball contact onto the pallet and the energy transfer in any type of exchange. However, the most remarkable point about this rubber is the further development of the sponge. The combination of open pores with an extremely elastic, but still tensioned rubber mixture, results in an explosive sponge conferring simultaneously power and playing sensation in all your strokes.
