The Cluster was specifically developed for the plastic ball. It was designed for disruptive players who prefer playing close to the table with long pimples and who attach particular importance on high control. Thanks to the moderate speed, topspin strokes can be returned short over the net with great precision. The non-slip pimple surfaces allow for a good spin reversal. The most effective attacking technique of the Cluster is aggressive pushing. In the ox version, the rubber is perfectly suited for a controlled, disruptive game close to the table, whereas the sponge versions also allow for a defensive game distant from the table with lots of rotation.
