Description

Key Features

  • High Elastic Co-Polyester Construction: Built using a multi-stage heating and cooling process that optimizes the molecular structure for a more responsive, “lively” feel.

  • Balanced Power and Control: Part of the Blackline Power series, designed to provide explosive “pop” on serves and groundstrokes without losing the directional accuracy of a premium poly.

  • Crisp, Comfortable Feel for a Poly String: Despite its aggressive texture, it offers a surprisingly dampened impact and a muffled sound that signals high-end shock absorption.

  • Good Durability and Tension Stability: Renowned for its “minimal tension loss” technology, allowing the string to play at its peak for significantly longer than standard textured polys.

  • Heptagonal Axially Twisted Profile: A 7-sided geometry that is twisted under high force to create a rough, gear-like surface for industry-leading spin and ball bite.

  • Available in Multiple Gauges: 1.17mm for maximum feel, power, and spin potential. 1.23mm for the “all-rounder” balance of durability and playability. 1.29mm for maximum control and durability for chronic string-breakers.

Best For

Intermediate to advanced players who want to wreak havoc on opponents with heavy topspin and “kick,” but still require a comfortable string that holds its tension.
