Description
Key Features
-
High Elastic Co-Polyester Construction: Engineered with a specialized additive package that increases the string’s flexibility compared to the original HEXtreme.
-
Balanced Power and Control: Delivers a slightly more “springy” response, providing easier depth on defensive shots while maintaining the surgical control Signum Pro is known for.
-
Crisp, Comfortable Feel for a Poly String: Offers a plush, “pure” impact sensation that filters out harsh vibrations, making it an excellent choice for players who want a shaped string without the stiffness.
-
Good Durability and Tension Stability: Features the legendary Plasma molecular cross-linking, ensuring that the string stays in its “peak playability” zone for a significantly longer time than other soft polys.
-
Hexagonal Profile for Consistent Playability: The sharp 6-sided geometry provides exceptional ball bite and “snap-back,” allowing for heavy topspin and a predictable launch angle.
- Available in Multiple Gauges: 1.20mm for maximum feel, power, and spin potential. 1.25mm for the “all-rounder” balance of durability and playability.
Best For
Intermediate to advanced players seeking a powerful, all-purpose polyester string that offers elite spin potential with a softer, more forgiving feel than traditional shaped polys.
