Performance ratings
Overview
Gosen AK Pro CX uses the unique Umishima (marine island) structure developed to enhance sharpness and high resilience. The CX fiber complements the nylon in durability and tension maintenance, creating the almost perfect tennis string with crisp and soft pocketing feel combined with polyester-like control. TW playtesters found it easy to keep the ball in play on full swings while maintaining comfort - impressive for a string with this much control.
