Strings Elite XT-firm co-poly with a six-pointed star shape

Diadem Elite XT is a firm co-poly with a six-pointed star shape.  Utilizing Star Core Technology, the string combines a low-friction surface with maximum ball bite. This string is stiffer than Solstice Power, which results in an explosive response off the string bed and long-lasting tension maintenance.   This string is ideal for advanced players looking for a solid feeling co-poly with incredible spin.Actual Cross Section Length: 40 feet / 12.2 m Color: Charcoal Gauges Available 18 (1.15mm) Best feel 17 (1.20mm) 16L (1.25mm) 16 (1.30mm) 15L (1.35mm) Most durable STAR CORE TECHNOLOGY Star Shaped Co-Polyester String This technology uses a six-pointed geometric cross section that equally distributes contact between strings, thereby minimizing friction significantly to allow for explosive snap back. At the same time the star shape provides a larger surface area creating more bite on the ball at impact to achieve maximum spin potential.
