The Mantra H is a 9.4-speed hard (47.5°) Japanese inverted tensor, discontinued.

The Yasaka Rakza Z is a hybrid tacky tensor (50° or 57° Extra Hard) with exceptional low-slip spin, good control, tacky topsheet, strong linear kick at full power, and excellent durability—demands full strokes and rewards aggressive play.

Mantra H is inverted and modern (discontinued); Rakza Z is tacky, heavy (72g) and built for proactive loopers. Both are hard, but Rakza Z has extreme spin and tacky feel while Mantra H has speed and inverted control. Choose Rakza Z if you prioritize heavy spin; Mantra H for speed.
