Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk wins by 12 points
Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 79/100 for the Vibor A Black Mamba Black Mamba Xtreme 3K 2.0. Its biggest edge is control (+11).
“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 Black Mamba Xtreme 3K 2.0 is the sharpest fang in Vibor-A's 2025 range: a 370 g diamond with an EVA core producing power 82 and a strike that arrives without introduction. The terms are the strictest kind: control 67, comfort 64, tolerance 63, numbers that assume complete technique and no arm complaints. Face details beyond the 3K designation are thin in our data. Value 74 is fair by brand standards. For devoted attackers drawn to the Mamba's mythology and able to meet its demands, the bite is authentic; everyone else should admire it from the demo bench.”
