Yasaka Rakza 7 Soft is a stepping-stone modern tensor with exceptional control and high spin production. Grippy topsheet enables easy brushing, and high throw angle with poly ball compatibility make it an ideal intermediate upgrade from beginner rubbers.

Yinhe Mercury II is an ultra-budget tacky rubber around five dollars per sheet with genuinely grippy topsheet and very high control. Elastic sponge is forgiving for beginners and defenders. However, it is slower than German tensors and rewards active strokes, lacking penetration at distance.

Rakza 7 Soft suits intermediate loopers wanting modern tensor performance and consistent spin. Mercury II suits budget-conscious beginners, defenders and choppers prioritizing spin and control over speed.
