Just Ten Colors K Evolution vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Just Ten Colors Black K Evolution 2022 is a mid-tier round-to-teardrop hybrid that attempts to blend control with moderate power but lacks the refinement of established brands at its price point. The EVA rubber core offers acceptable comfort over extended play, but off-centre shots feel inconsistent and the carbon layering feels generic rather than purposefully engineered. Recreational players looking for a branded-looking racket on a tight budget might find it passable, but intermediate players will quickly outgrow its limitations and feel underwhelmed by its vague feedback.”

“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.”
