Friendship 729 · 729 Classic · Inverted

R.I.T.C. 729

The classic tacky inverted covering from Tianjin 729. It produces heavy spin on serves and opening loops with a low, controlled arc, and rewards players who accelerate through the ball rather than rely on the sheet's own speed.

Variants and configurations

60 variants

Colour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.
