Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk vs Vibor A King Cobra Technic

“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 King Cobra Technic is Vibor-A's most demanding card in this range: power 83 paired with the harshest terms we regularly see: control 66, comfort 62, tolerance 61, and maneuverability 64. Every number outside the power column is a warning. Weight documentation is incomplete. Value 74 prices the fang fairly by brand standards. The honest review: this frame hits tremendously and forgives nothing whatsoever, and its intermediate label is aspirational at best. Strong, technically complete attackers who want the Cobra's most vicious recent edition will find it here; everyone else will find physiotherapy.”
