Full Review

Technifibre X-One is one of the stiffest polyester strings available, making it ideal for advanced players who prioritize spin and control. The string's octagonal shape and high stiffness create exceptional spin potential, allowing players to hit aggressive topspin shots. While durability is excellent, the comfort level is very low, making it unsuitable for players with arm issues. This string is best for tournament players who can handle the harsh feel in exchange for superior performance.
