Yasaka Rakza 7 Soft scores 8.2 and delivers exceptional control that consistently outscores comparable tensors in user reviews. High spin production benefits from easy brush activation due to grippy topsheet, and high throw angle provides generous net clearance for topspin loops. Works exceptionally well with new poly balls thanks to soft sponge, with excellent serve and receive game for precise short flicks. Great value relative to premium tensors and performs reliably on both backhand and forehand. However, lower speed than standard Rakza 7 and most high-end tensors struggles with penetration from mid-far distance.

Bluestorm Pro AM delivers higher speed and versatility across all distances while maintaining excellent control and spin. Both suit intermediate players, with Rakza 7 Soft emphasizing control and Bluestorm Pro AM offering balanced modern performance. Soft suits control-first players and backhand specialists; Bluestorm Pro AM suits all-rounders seeking balanced offensive capability.
