Siux Electra Pro 2026 Fire Red

The Electra Pro in Fire Red is a lot of racket for the intermediate bracket it is aimed at: power 90 from the EVA core and Carbon 12K face means short lobs get finished properly, and the even balance keeps the frame from feeling like a sledgehammer between shots. Control 78 is trustworthy on drives. The warnings are the usual ones at this output level: comfort 67 is firm for players still building technique, and tolerance 66 will punish the mishits that intermediates naturally produce. If you are an improving attacker with sound basics, it is a thrilling step up; if your contact is still streaky, demo first.

Siux Electra St3 Stupa Pro

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.
