Wobbler is a long pimpled rubber and one of the first pimpled rubbers specifically developed for the plastic ball. It was designed for disruptive players close to the table.
The slightly grippy, medium hard pimple surface enable players to perform very good pushing strokes that are difficult to return.
Moreover, the rubber allows for very short passive blocking right over the net. However, when playing more actively, players can also perform long shots that are diffcult to predict.
The ox version is suited for active disruptive players close to the table. The sponge versions offer more potential for attacking options.
