A 300 g, 100 sq in option to compare spin and rally-ball shape. This assessment uses published specifications, not a play-test.

Who should demo it?
Try the SX 300 if you want to compare spin and rally-ball shape and can handle its 300 g nominal frame weight throughout a full session.
What to watch for
Check depth and directional control with your normal swing. Published weight and head size cannot predict your own result.
Demo against
Babolat Pure Aero Gen9 — 300 g / 100 sq in; compare handling and depth with the same strings.
Head Extreme MP 2026 — 300 g / 100 sq in; compare handling and depth with the same strings.
A useful on-court test
Compare rally depth, firm returns, second serves and quick exchanges. Finish with points after at least 30 minutes; check that preparation still feels comfortable. Use comparable strings and grip sizes, and take your current racket as the baseline.
See the published specification table above. Swingweight and UK grip-specific availability are not established by the manufacturer reference; confirm them before ordering.
Ask for the bumper, throat, both sides of the hoop, grommets and grip butt in clear photos. A is excellent cosmetic condition, B shows normal wear, C needs a closer cost check; structural damage is a reason to walk away regardless of price. A grade does not establish authenticity or structural safety.
