Babolat Technical Viper 3.0 scores 91/100 against 87/100 for the Siux Electra St3 Stupa Pro. Its biggest edge is power (+8). The Siux Electra St3 Stupa Pro answers back on sweet spot (+5).
“The Technical Viper 3.0 is the bluntest instrument in Babolat's range and makes no apology for it. Head-heavy, diamond, Black EVA behind a Carbon 3K face: swing hard and the ball leaves at 94-power pace, the highest tier we score. Everything else is the price of admission. Control 74 asks you to aim with your feet, comfort 62 makes it one of the harshest hits at tour level, and tolerance 61 turns mishits into nothing balls. Maneuverability 66 means late reactions at the net stay late. For a physically strong, technically clean attacker it is devastating. For anyone else it is a fast route to a sore elbow.”
“The ST3 Stupa Pro is where Stupaczuk's Siux line found its voice: a hybrid head with an even balance and an EVA core that hits harder than its manners suggest. Power 86 finishes points, and the frame stays composed enough through transitions that control 75 feels understated in practice. Comfort 67 and tolerance 66 keep it in firm territory, and the strike rewards conviction. Two generations on, pricing has settled at genuine-bargain levels (value 76). For advanced players who want signature-line aggression without current-season cost, the ST3 has aged into one of the smarter buys.”
