Babolat Technical Viper 3.0 vs Siux Electra ST4 Pro Stupa

“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 ST4 Pro Stupa is Stupaczuk's 2025 frame with the confirmed vitals of a modern attacker: even balance, 365 g, and a scorecard that reads first-strike padel. Power 88 converts pressure into finished points, control 76 keeps heavy drives inside the lines, and comfort 67 with tolerance 66 tells you the strike is firm and honest about mishits. Beyond weight and balance, the full specification is unconfirmed, so demo before committing. Value 78 reflects the run-out pricing on last season's signature line: for aggressive all-courters, it is a lot of racket for the money.”
