Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 82/100 for the Vibor A Black Mamba Radical 12K 2.0 2025 P. Its biggest edge is power (+5). The Vibor A Black Mamba Radical 12K 2.0 2025 P answers back on comfort (+8).
“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 Radical 12K 2.0 is the prior generation of Vibor-A's Black Mamba attacking racket — same teardrop shape and medium-high balance, with slightly less refined surface technology than the current 3.0 release. PRR score: 82/100.”
