Siux Electra St3 Stupa Pro vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“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.”

“Franco Stupaczuk's Shadow Red ST5 is built to attack: power 90 with control 78 is a proper first-strike profile, and the confirmed even balance at 365 g explains why it feels quicker between shots than its hitting power implies. Blocks and counters stay manageable, then the same frame turns a short lob into a finished point. The firm side is unavoidable: comfort 67 and tolerance 66 mean mishits are felt and punished. Beyond balance and weight, full spec for this colourway is unconfirmed, so try before you buy. For aggressive all-court players it is a convincing signature frame.”
