The M1 (8.4) reaches 9.7 speed with a high throw angle designed for explosive loops close-to-mid table from advanced players. The Rakza Z (8.6) trades speed (medium) for exceptional spin output (extreme) and a hybrid tacky-tensor feel that rewards full committed strokes. M1 is a pure speed-and-angle tensor; Rakza Z is a heavy, grippy alternative to boosted Hurricane 3 or Dignics 09C for forehand loopers who want maximum spin stability. Pick M1 for pace and catapult; pick Rakza Z for spin-driven pressure play and defensive stability, accepting that it demands more arm/wrist engagement and plays weak at less than full power.

FAQ

Which rubber generates more spin?

Rakza Z generates extreme, low-slip spin on loops, backspin openings and serves—noticeably more than the M1’s very high spin at 9.0. However, Z requires full strokes to unlock it.

Which is faster?

Bluefire M1 is significantly faster at 9.7/10 versus Rakza Z at medium speed. M1 is designed for pace-based attacking; Rakza Z is slower but compensates with exceptional spin gripping.

What’s the weight penalty?

Rakza Z is notably heavier at 72g uncut versus M1 at around 49g. This can cause arm/wrist fatigue, especially on carbon blades, and is a real consideration for players with mobility concerns.
