Description Now with a harder version of the “Spring Sponge X”, Dignics 09c offers more spin value, creating a greater curved trajectory. The sticky surface and harder sponge will give players more control for an attacking topspin game. The pimple size has been adjusted to be thicker at the base, creating a safer counter-topspin and greater control to change the speed of the ball. Speed 9.6 Spin 9.8 Control 9.5
