Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk vs Vairo Karbon Speed

“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 Karbon Speed is Vairo's value attacker: an even-balanced hybrid with an EVA core scoring power 75 with fair terms (comfort 67, tolerance 66) and honest handling (69). Control 68 is workable. Weight and face documentation is incomplete, so check the specimen. Value 82 is the persuader: Vairo's Argentine heritage and construction at arithmetic that matches the value establishment. The brand's European network is thinner than its South American reputation, the familiar challenger trade. For improving attackers who enjoy a badge with genuine history that most clubs have never seen, a sound, keen buy.”
