K.O PRO is half-long pips rubber that can be considered a faster version Dr.Neubauer's K.O. This version allows for an even more dynamic game while counterattacking and flat hitting. At the same time, this new version also provides a bit more "sinking effect" on the ball than the original version can. This holds true for all active shots but also for passive blocking. This makes it a good alternative for players who enjoy using K.O. but are looking for more speed to improve their attacking game, without its disruptive effect. The thinner sponge versions (1.3mm and 1.5mm) provide maximum control and disruptive effect, while the thicker versions (1.8mm and 2.0mm) naturally offer greater speed.
