Friendship/729 Fx Super

Based on the name “Fx Super,” and assuming it’s a relatively modern rubber, we can infer some likely characteristics even without knowing the brand.

The “Fx” designation often suggests a focus on speed and spin, making it highly probable that the rubber type is inverted (smooth). We can expect the playing characteristics to lean towards offensive play. “Super” further reinforces this, implying enhanced performance in these areas. Therefore, it’s likely a medium-fast to fast rubber with high spin potential and decent control. The rubber is probably designed for players who prioritize attacking, looping, and driving the ball. It would suit players who like to generate their own power and spin and are comfortable with a slightly less forgiving rubber. Due to the “Fx” designation, it’s likely the sponge hardness is medium to medium-hard.

While specific technologies are unknown, we can speculate. The rubber likely incorporates a tensioned top sheet to enhance spin and speed. The sponge could feature a larger pore structure to improve energy transfer and responsiveness. It might also have a slightly tacky surface to further aid in spin generation. Given the “Super” moniker, the manufacturer likely aimed to create a rubber that offers a balance between speed, spin, and control, making it a versatile option for offensive players looking to elevate their game. It’s likely designed to be used on both forehand and backhand, although some players might prefer it more on their forehand due to its offensive capabilities.
