Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk vs Vibor A Vibor-A Yarara Radical 12K 2.0

“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 Yarara Radical 12K 2.0 is defined by its aggressive hybrid geometry that channels decent pop from the EVA core into a workable smash platform for advancing players who want to punch above their control level. The even balance keeps it more manageable than a full diamond power frame, though the 12K carbon face delivers a firm, feedback-heavy feel that will fatigue arms prone to sensitivity over extended sessions. Argentine club players and competitive intermediates pushing toward advanced who prioritize offensive punch over precision touch will find it a credible, well-priced option within the Vibor-A lineup.”
