Nox La10 Quantum 12K By Leo Augsburguer vs Siux Electra ST5 Pro Shadow Red 2026 Franco Stupaczuk

“The LA10 Quantum 12K is a raw power weapon built around a hard 12K carbon face and head-heavy diamond shape that delivers explosive smash pace and deep drive penetration when struck cleanly. The 375g head-heavy construction punishes off-centre contact and demands strong wrist conditioning, making it a genuine specialist tool rather than an all-rounder. Advanced offensive players with a polished technique who prioritise destroying the ball from the back court will find it deeply satisfying, but those needing forgiveness or fast net reactions 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.”
