Rakza 7 (8.6 rating) leads with huge grip and spin from natural-rubber topsheet, approaching Tenergy 05 spin levels with outstanding control, consistency, and excellent short-game performance—no runaway catapult on touch play. It is available in three thicknesses to tune speed against control, works on both wings, and represents exceptional value with strong durability.

Glayzer (8.2 rating) offers consistent Butterfly technology, though Rakza 7 delivers more raw spin and gripping feel. Rakza 7 speed is moderate—around 80 percent of top rubbers—requiring technique-based placement, and it reacts to incoming spin, demanding clean technique and regular cleaning. Glayzer is faster overall and requires less maintenance.

Choose Glayzer for accessibility, durability, and broad technique tolerance. Choose Rakza 7 if you want near-Tenergy spin with excellent control and value, especially for backhand play where it is highly recommended at club level.
