729 HIGHER WITH TRANSCEND SPONGE
A thinner more elastic top sheet allows this rubber to load up like a spring, creating large amount of spin with less effort. Works great with or without glue. Deadly for serve and return, but also plays well mid distance. Transcend is lighter and faster than traditional Chinese sponges. Sponge stores energy to release into the ball, while most sponges allow energy to dissipate.
