Butterfly Super Anti is a special rubber that does not react the way most others do. In today's game, which is dominated by high tension rubber sheets that produce inordinate amounts of speed and spin, Super Anti is the outlier. This Butterfly rubber is designed to take all the sting out of your opponents attacks and give them nothing to work with. Due to the nearly frictionless topsheet and soft sponge, Super Anti neutralizes your opponent's fast and spinny shots. The result is a much slower return with little to no spin, giving your opponent fits that most can't handle. The best way to utilize this special rubber is to have a fast, spinny, offensive rubber on the other side of your racket to keep your opponent off balance. Advanced players can use this difference to their advantage by twiddling (switching which side of the paddle is on the forehand and backhand by spinning the paddle in their hand) during the point, adding another level of mental gymnastics for whomever they are playing.
