The Mizutani Jun Super ZLC features a tighter weave of ZL Carbon resulting in a massive sweet-spot which is almost the entire face of the racket. As fast as, but not as hard/stiff of a feel as most pure Carbon fiber blades. The Tenergy 05 rubber is widely used by many top players. The patented Spring Sponge technology offers tremendous speed and feel and the 05 offers the most spin in the Tenergy series.
