Babolat Viper Soft Juan Lebrón 3.0 vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Viper Soft Juan Lebrón 3.0 takes the same 365g Black EVA formula that already works on the Technical Viper Soft and wraps it in Juan Lebrón's signature diamond shell. Power eases back from the standard Viper JL's tour-level peak to a still-strong 82, and in exchange control and comfort both climb into the high 70s/80s — a genuinely balanced racket rather than a compromise. Maneuverability improves too, so the head-heavy diamond feels less punishing to hustle at net. The catch is coverage: it is stocked at a single retailer so far, and priced at parity with the far more aggressive standard Viper JL, so this is not the discount play the Technical Soft is.”

“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.”
