RAKZA 7 Soft is one of the popular rubbers in the Rakza family using mainly natural rubber gum for the top sheet. This improves the level of grip and the power of spin drastically. The top sheet is combined with the new ?Power Sponge?. The top sheet and ?Power Sponge? work in perfect synergy, producing the Hybrid Energy rubber. In Yasaka RAKZA 7 Soft the top sheet is the same as for RAKZA 7. The sponge is softer which gives the rubber more sound and bulit-in speed glue effect. With RAKZA 7 Soft the control characteristics are improved. After hitting the ball with top spin the curve of the ball is slightly higher, giving little bit bigger margins in the game. In the short return play, the ball feel is better.
