Babolat Stima Energy vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Stima Energy is Babolat's featherweight peacemaker: 345 g, among the lightest frames we score, with an EVA core tuned so control 82, comfort 78 and tolerance 79 make every session gentle. Maneuverability 80 is the standout: the frame is simply always ready. Power 68 is the transparent cost. Value 78 keeps the arithmetic kind too. This is the racket for players recovering from injury, managing a shoulder or elbow, stepping up from beginner gear, or anyone who values never being late over ever hitting hard. Within that brief it is close to faultless; outside it, predictably outgunned.”

“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.”
