Friendship 729 Battle Taichi 39/37

The iconic Battle series — celebrated for its raw pop, tacky spin, and dependable control — is reborn with Battle Taichi. Designed for players who trusted Battle II and Battle III for forehand power loops, this new version features an innovative dual-layer sponge (39/37°) that blends firmness and softness in one rubber. The result is the same explosive spin and power of the originals, now enhanced with greater versatility: delicate touch in the short game, crisp attacking strokes, and improved control when changing tempo.

• Color options: Blue rubber comes with a blue sponge and blue-themed packaging; red rubber comes with a red sponge and red-themed packaging.

• Sponge structure:

  • The first number = outer sponge layer (closer to the topsheet).

  • The second number = inner sponge layer (closer to the blade).

39/37 → harder outer layer (39°) + softer inner layer (37°)

• Feel: The ball meets the firmer sponge first, giving a crisp, direct response for drives and blocks. The softer inner layer adds dwell time when you hit through, generating more spin.

37/39 → softer outer layer (37°) + harder inner layer (39°)

• Feel: Softer surface touch enhances control in short play, flicks, and opening loops. When the shot is stronger, the firmer inner layer engages, providing extra power and stability.
