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

“The Tech Viper Soft is the Viper for humans. Babolat keeps the head-heavy diamond silhouette and Black EVA core but tunes the 365 g build toward mercy: comfort 76 and tolerance 74 are numbers the standard Viper cannot dream of, and the strike goes from punishing to merely assertive. The scores meet in the middle at power 82 and control 82, a genuinely balanced split that suits attack-minded players whose elbows have opinions. Maneuverability 72 is respectable for the shape. You give up the 3.0's brutality; you gain a racket you can play three times a week. Value 74 seals a sensible deal.”

“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.”
