Butterfly Challenger Attack Table Tennis Rubber is a pimples-out rubber ideal for quick attacks. However, due to the amount of spin that can be generated (more than traditional short pips rubbers), you can also use it for a controlled allround game as well. With this versatility, players of a variety of levels and playing styles can benefit from what Challenger Attack has to offer. With a sponge that is just barely softer than the Tenergy line, one also has exceptional feel on their shots, helping to place pushes and attacks right where they are needed.
