The PRO/TOUR version upgrades the iconic square racket head to create a larger and more fault-tolerant sweet area. The thickened design on the side of the racket frame enhances the rigidity of the racket frame. The racket stick is made of EXTRA SLIM SHAFT, which is thinner than the old model, for a better swing experience. And the power conversion cone cover PLUS is used to bring better racket curvature and rebound. These technical changes make the smash more powerful and the swing more fluid, resulting in better racket performance for high-level players.
