Friendship/729 Bluesponge

The “Bluesponge” rubber, while lacking a known brand, is likely an inverted rubber designed for offensive play. The name “Bluesponge” strongly suggests a blue-colored sponge, a common feature in modern table tennis rubbers often associated with enhanced elasticity and a lively feel. Based on this, we can infer that the Bluesponge rubber probably prioritizes speed and spin. It likely offers a good level of spin generation, allowing for aggressive topspin attacks and controlled serves. The speed would be above average, enabling players to drive the ball with power and maintain a fast-paced game. Control, while not the primary focus, would likely be decent enough to allow for consistent shot placement, especially for players with good technique.

Given the likely characteristics, the Bluesponge rubber would be best suited for aggressive players who prefer to attack with topspin from both forehand and backhand. Loopers, drivers, and counter-attackers would find this rubber beneficial. The sponge hardness is difficult to determine without further information, but the “Bluesponge” moniker often implies a medium-hard sponge, offering a balance between speed and control. It’s unlikely to be extremely soft or extremely hard. While specific technologies are unknown due to the lack of branding, the blue sponge itself could be considered a special feature, potentially incorporating a unique cell structure or chemical composition to enhance its elasticity and responsiveness. Ultimately, the Bluesponge rubber appears to be a performance-oriented option aimed at offensive players seeking a blend of speed, spin, and reasonable control.
