Most players have already adjusted to the new ABS balls successfully and made the necessary changes in their techniques. At the beginning of this adjustment, players preferred rubbers with rather soft top sheets (for more ball rotation and speed), but now top-level players more and more use hard to very hard rubbers which perform at their best in close-to-the-table power play. In order to offer the perfect solution on this level, too, GEWO designers and world-class players as well as ambitioned players of all levels teamed up in countless test series to find the perfect rubbers meeting the specific requirements of the individual players. The goal was to find the ideal combination of maximum speed, spin and feeling without losing the indispensable level of control required in table tennis.
