Description

Key Features

  • High Elastic Co-Polyester Construction: Manufactured using a specialized high-tech heating process that eliminates the “brittleness” found in first-generation polyesters.

  • Balanced Power and Control: Offers a medium-firm response that provides pinpoint accuracy for big hitters, while the “Plasma” additives offer a subtle energy return.

  • Crisp, Comfortable Feel for a Poly String: Delivers a distinctive, clean “snap” at impact with reduced vibrations, making it much more arm-friendly than traditional stiff spin strings.

  • Good Durability and Tension Stability: Features Signum Pro’s industry-leading molecular cross-linking, resulting in virtually zero initial tension loss and a long playability life.

  • Hexagonal Profile for Consistent Playability: A sharp, 6-sided geometric shape designed to grip the ball’s felt for massive topspin without sacrificing the 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. 1.30mm for maximum control and durability for chronic string-breakers.

Best For

Intermediate to advanced players seeking a powerful, all-purpose polyester string that provides elite spin and the best tension maintenance in the “shaped string” category.
