K.O. PRO provides a "sinking effect" of the ball while blocking passively.
The rubber is also very effective for service returning and pushing.
At the same time the ball can be accelerated easily through aggressive counter-attacking and hitting, with good control.

This makes it a good alternative for players who are using half-long pimples for both disruptive blocking and powerful attacking.
The thinner versions (1.3 and 1.5mm) offer the best control and disruptive effect, while the thicker versions (1.8 and 2.0mm) are naturally faster .
