Gamma adds another member to its legendary TNT family! Named TNT2 React Pro this premium synthetic gut benefits from Gamma's time-tested TNT2 technology  giving it better feel and energy return. What separates React Pro is the unique low-friction surface, which enables the strings to snapback viciously at impact (think spin). In addition to delivering above average spin-potential for a synthetic gut, this string resists frictional notching, resulting in greater durability.
