Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk wins by 15 points
Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 76/100 for the Tecnifibre Curva Power. Its biggest edge is power (+13).
“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.”
“The Curva Power is functionally the Curve Power's twin at 365 g: the same foam core, the same 18K face, the same 77/67 power-control split and firm terms (comfort 66, tolerance 65). Value 70 trails its sibling slightly on current pricing. Two listings this close from one brand usually means regional naming; the practical guidance is identical either way: an 18K face at accessible money for improving attackers who want Tecnifibre's clean report, bought at whichever listing prices lower. Check the specimen's actual weight and buy the cheaper twin.”
