Nox At10 Genius 18K Alum By Agustin Tapia vs Siux Electra St3 Stupa Pro

“Tapia's AT10 Genius 18K Alum is the rare frame that hits like an attacker's racket but doesn't fall apart when you defend. The 18K carbon face over a black EVA core gives a dense, springy strike: drives carry pace (power 88), yet the teardrop shape and even balance keep the head obedient on bandejas and blocks (control 84). It sits at the top of our table because it asks fewer sacrifices than a pure diamond. The compromises are familiar: comfort 70 means the stiffness reaches your elbow eventually, and tolerance 68 still wants near-middle contact.”

“The ST3 Stupa Pro is where Stupaczuk's Siux line found its voice: a hybrid head with an even balance and an EVA core that hits harder than its manners suggest. Power 86 finishes points, and the frame stays composed enough through transitions that control 75 feels understated in practice. Comfort 67 and tolerance 66 keep it in firm territory, and the strike rewards conviction. Two generations on, pricing has settled at genuine-bargain levels (value 76). For advanced players who want signature-line aggression without current-season cost, the ST3 has aged into one of the smarter buys.”
