Just Ten Reborn Killer vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Just Ten Reborn Killer 2022 is a mid-range diamond-shaped racket aimed at aggressive intermediate players seeking punch over finesse, but it falls short of delivering a truly distinctive feel in either power or control. The EVA rubber core provides moderate pace but the frame lacks the precision engineering of top-tier brands, resulting in a somewhat generic response that neither excites nor offends. Players on a tight budget who want an attack-oriented shape may find it serviceable, but most intermediates would be better served by comparable offerings from more established manufacturers at similar or slightly higher price points.”

“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.”
