Etika Pro H (51°) is a hard sponge version that maximizes the power of topspin by fully utilizing the ability of a high-grip top sheet. Compared with the medium sponge version - Etika Pro (47°), Etika Pro H (51°) can create heavier rotation from the identical strength of impact between the ball and the rubber. Also, the hard sponge lets the player easily control the trajectory of the topspin, while increasing the precision of passive block or on-table technics simultaneously. Etika Pro H (51°) is recommended for highly skilled players who want to dominate the rallies with the power of topspin. Made in Japan.
