RadSpeed

Front-biased radial weighting (28g forward, 10g back) yields a forward CG that prioritises ball speed and low spin over MOI — measured around 5,400 g·cm², comfortably below the post-2024 10k generation. Reviewer testing confirmed forgiveness "preserves both direction and ball speed on mis-hits" via radial back weighting and face technology, but the XB sibling is the family forgiveness leader; the standard model sits a tier below by design.

Independent robot testing ranked the head among the top 5 drivers for total distance at mid swing speeds in its launch year. Engineered for ~300rpm less spin than the predecessor SpeedZone, delivered via 28g forward CG mass and an Infinity-milled face. Launch-monitor testing on Foresight GCQuad confirmed "considerably less spin" vs the SpeedZone in low-spin configuration. Lower-launch / low-spin profile rewards 100+mph swing speeds with strong total yardage.

MyFly hosel with 8 settings (including DRAW positions) plus interchangeable sole weights (gram values 2 through 16) gives the player meaningful shape-tuning tools. Forward CG plus a compact-feeling 460cc footprint enables both starting-line control and on-demand fades. A tour-staff player at the time specifically cited workability and "the ability to execute a butter cut safe shot" with the RadSpeed platform.

Impact reads solid, firm, and dense — "one of the most solid or dense-feeling drivers tested" — with a clean hot-off-the-face character rather than a hollow slap. Reviewer testing noted hammer-like feel with cleanly differentiated centre-vs-miss feedback. A premium tactile profile for the 2021 generation that ages well.

Acoustic profile reads higher-pitched, muted and strong — a sharp, staccato "snap" rather than a hollow boom. Reviewer testing compared it to "the 'crack' of a mallet hitting a solid piece of padding" — confidently struck rather than tinny. Higher-pitched than modern tour-correct profiles but consistent and satisfying at impact.

Compact-feeling 460cc footprint with a bold black/yellow colourway and a CNC milled face that "offers sneaky alignment assistance, framing the ball at address." Carbon-fibre wrap crown (6g lighter than the predecessor) cleans up the silhouette. Industry panel testers highlighted aggressive shaping that reads better-player rather than oversized — bolder than tour-spec but cleaner than typical game-improvement footprints.
