Quad Shark vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Quad Shark is a mid-range diamond-shaped racket oriented toward power generation, but its identity is muddied by an inconsistent sweet spot and modest build quality that limits confidence on off-center strikes. The aggressive frame geometry hints at smash potential, but the lack of refined core technology means advanced players will find it punishing and unpredictable rather than rewarding. Budget-conscious beginners or casual players wanting a power-leaning shape without a premium price tag are its most forgiving audience.”

“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.”
