Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk scores 91/100 against 77/100 for the Vibor A Black Mamba Elite 3K 2.0. Its biggest edge is control (+11). On price, the Vibor A Black Mamba Elite 3K 2.0 is currently €32 cheaper.
“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 Elite 3K is a punchy hybrid-shape power racket from Vibor-A that delivers genuine pop on smashes and drives, aided by its 3K carbon construction and EVA core tuned for explosive rebound. The even balance keeps it more manageable than a full top-heavy diamond, but off-centre shots can feel unforgiving and the stiffer 3K layup transmits vibration noticeably over longer sessions. Aggressive intermediate-to-advanced players who prioritise attacking play on a budget and can handle a smaller effective sweet spot will find it a compelling proposition.”
