Osaka - Pro Tour Ltd - Power | Silver Lake Blue vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The Osaka Pro Tour Ltd Power leans hard into aggressive shot-making with a diamond-leaning shape and stiff frame, delivering decent pace on smashes but punishing off-center strikes with noticeable arm feedback. The 'Silver Lake Blue' limited edition colorway adds visual appeal but masks a racket that sits firmly in the mid-tier category, where it struggles to justify its price against more established Spanish or Argentinian brands with proven performance pedigree. Intermediate to advanced players seeking raw power might find moments they enjoy, but arm-sensitive players or those prioritizing consistency should look elsewhere.”

“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.”
