The new rubber K.O. comes in addition to our half-long pimple rubber AGGRESSOR which we launched 2016. While AGGRESSOR is most effective while playing actively (active blocking, counter-attacking, hitting) the new K.O. also produces a distinctive disruptive effect with low bounce while blocking passively. Also K.O. provides great control, including and especially for service returning and pushing over the table. This makes K.O. a very effective half-long pimple rubber with great control.
