Specs and features: Colored string rolls now available! String performance ■GOSEN rates string performance on the following four characteristics. Each characteristic is rated on a 10-point scale, and the higher the number, the better. These ratings compare products within the same string series, not across all GOSEN strings. [Durability] Indicates the strength of the string. GOSEN fires tennis balls at 100 km/h for nylon strings and 120 km/h for poly strings, and uses the number of hits until the string breaks as the measure. The higher the number, the better the durability. [Repulsion] Indicates how far and how crisply the ball flies. The coefficient of restitution is measured using GOSEN's own method. The higher the number, the farther the ball flies. [Softness] Indicates how soft the feel is. It is rated using stiffness values from physical testing and players' impressions from human testing. The higher the number, the softer the feel. [Spin/Drive] Indicates how much spin the string puts on the ball. It is rated from spin rates in high-position and low-position drop tests. The higher the number, the more easily spin and drive are applied.
