SpinLord Keiler is a fast medium pips rubber. It combines a soft topsheet with a medium-hard sponge. Keiler can be used both for attack and defense. Blocking, chopping, counter attacks, hard drives; almost everything is possible with this rubber (only playing topspins with this rubber is more difficult). Keiler is more of a rubber to confuse the opponent by playing a mixture of passive blocking and active counter attacks.
