Genesis Hexonic Power is a co-polyester string. Co-polyester suits competitive players who prioritize control and spin — its low-powered character rewards full, aggressive swings. See community reviews for individual player feedback.
Durability varies by swing speed, string pattern, and play frequency. Co-polyester strings like Hexonic Power are among the most durable options available, though they lose tension faster than other materials. See the characteristic scores above.
Co-polyester strings are generally stiffer and can increase arm stress at high tensions. Players with elbow or shoulder concerns should string Hexonic Power at the lower end of their racket's recommended range, or consider a multifilament or natural gut alternative. Always consult a professional for tennis-related injuries.
Start in the middle of your racket manufacturer's recommended tension range and adjust to taste. Co-polyester typically performs better at slightly lower tensions — this increases comfort and maintains the string’s control properties longer.
