Where it wins
- Looks88
- Feel86
- Sound85
Watch
Rated highest for looks and feel; its softest dimension is workability.
You strike it reasonably well and want a straight, stable, low-spin driver with a fast face and a fine feel.
You need the very most forgiveness (a max-GI head), a draw bias (the ST-X), or full adjustability (the ST-G).
Pros
- One of the straightest, most consistent drivers of 2023 — a stable, low-spin all-rounder
- The face-side chamber adds real ball speed over the 220, with rock-steady low spin
- A lively feel on the middle and one of the sleekest looks of its year
Cons
- Above-average, not max, forgiveness — a dedicated GI head is steadier
- Off-centre feel and sound go noticeably dull
- Neutral and stability-first, with no movable weights
By dimension
Forgiveness
StrongAbove-average and dependable — high MOI keeps it straight off-centre, holding ball speed especially low on the face, if short of a max-GI head.
Distance
StrongGenuinely fast — the new face-side insert lifts ball speed over the 220, and the low spin stays put rather than jumping up to steal carry.
Workability
ModestNeutral and straight-first, though a deeper, more compact head lets a good player nudge it a touch either way.
Feel
ExcellentBouncy and quick off the sweet spot — the ball springs away, but a miss turns lifeless and flat underhand.
Sound
ExcellentA low, popping report with a soft ringing edge — easy on the ear, well short of shrill, and duller on a miss.
Looks at address
ExcellentOne of the classiest heads of its year — a round, tall-faced profile that looks trimmer and dearer than its volume suggests.
