ACUDA S1 is a very fast rubber with outstanding spin qualities. Close to or away from the table it is possible to play "loop-loop" as in the days of speed glued rubbers. Despite its medium hard sponge ACUDA S1 is easily controllable and has a great feel. You can count on ACUDA S1 even in an awkward situation. This rubber may be fast but ball control is excellent. Basic character: spin-optimized, high precision fast rubber. Player's style: aggressive, first ball attack, close to the table with maximum arc.
