Paired with the 729 Sponge, this Chinese classic offers swift and forceful performance while maintaining control. The 729 FX excels in swiftly generating offense and spin. Its sensation closely resembles that of the RITC 729, though it boasts a slightly higher spin capability while maintaining a comparable speed to the classic RITC 729. The FX edition retains the classic 729 feel but enhances spin production. If seeking an all-round rubber prioritizing topspin attacks, the Super FX stands as an excellent option. It has likely been the top-selling reverse rubber globally since the 1970s.
