The New Spin Machine!
No speed glue is needed! Trough continues testing it has been possible to concentrate the "tension increase" on the spin factor. Until now , "tension rubber" concentrated on increasing spin and speed equally but with the Yasaka concept the "spin tension" increase by 2/3rd and the speed tension increased by 1/2. XTEND does develop superior spin characteristics especially useful for the 40 mm ball.
