Dr. Neubauer BISON+ rubber is an improvement of the well-known rubber Bison. BISON+ comes with a softer touch and thus a bit more control. An Anti-Topspin type rubber, it will literally "kill" the speed of the oncoming ball while blocking thanks to the absorption power of its dampening sponge, even when used on fast and stiff offensive blades. Also, BISON+ will help you to perform pushing and lifting (especially on chopped balls) as well as slow counter-attacking against float balls.
The Dr. Neubauer Anti-Spin rubbers BUFFALO+, BISON+, and RHINO+ are renowned to be highly effective when used with celluloid and plastic balls. However, they are probably the only rubbers currently on the market that also produce good spin reversal and a low bounce with the new ABS balls.
All in all, BISON+ is easy to handle and provides both great control and maximum spin reversal even on fast blades.
