Siux Electra 4 Flow vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Siux Electra 4 Flow is a forgiving hybrid-shaped racket built around an EVA foam core that delivers a smooth, consistent feel with a generous sweet spot, making it accessible for beginners who want a confidence-boosting tool without harsh vibration. Its even balance keeps it maneuverable at the net, though at 375g it sits on the heavier side for a starter racket, slightly limiting wrist-driven reactions during fast exchanges. Players just starting out who prioritize arm comfort and error tolerance over raw punch will find it a solid choice, though at its price point the competition from brands like Babolat and Head offers arguably more refinement for the investment.”

“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.”
