Siux Electra ST4 Rulo vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Siux Electra ST4 Rulo is a mid-range teardrop-leaning hybrid that prioritizes a blend of offensive bite and decent maneuverability, with the Rulo (cylinder) foam core giving it a somewhat lively but imprecise rebound feel compared to EVA-based alternatives. It plays best for intermediate players around the 3.0–4.0 level who want some pop without committing to a full aggressive diamond shape, though the PadelPROShop exclusive branding adds little functional differentiation beyond aesthetics. The comfort and sweet spot tolerance are acceptable but not exceptional, meaning players with arm sensitivities or those who frequently mishit will find better options in this price bracket from brands like Bullpadel or Head.”

“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.”
