This ethylene string has a characteristic, hexagonal profile which provides extra grip on the ball's felt, producing optimum spin. A positive side-effect of this surface structure is that the string notches quickly, preventing slippage. The Polyfibre Hexablade feels slightly stiffer than other strings, but thanks to Polyfibre's Standardized Molecular Distribution Technology (SMD) it is extremely durable and its high dynamic elasticity makes it particularly easy on the arm. A string designed especially for topspin players looking for maximum spin and optimum control for minimum effort.
