These target opposite play styles. Tenergy 05 FX (8.4) is soft, backhand-specialized, and rewards technique and touch. Rakza Z (8.6) is a hard tacky hybrid at 50 degrees optimized for forehand, delivering exceptional low-slip spin and strong linear kick on full strokes.
Tenergy 05 FX excels at dwell, flicks, and touch. Rakza Z delivers extreme spin on loops, backspin openings, and serves with tacky topsheet that grips the ball and makes lifting heavy backspin easy. However, Rakza Z is heavy at 72 grams, requires a more closed blade angle due to high throw, and is weak and slow at less than full power or when out of position.
Pick Tenergy 05 FX for soft, dwell-based backhand control and consistency. Choose Rakza Z if you are a proactive offensive forehand looper who wants heavy spin and placement and is happy to swing fully, accepting the weight penalty.
