Where it wins
- Looks92
- Feel88
- Sound86
Watch
Rated highest for looks and feel; its softest dimension is forgiveness.
You're a strong striker who wants to fine-tune a fast, low-spin flight and shape it at will, with a soft feel.
You want easy forgiveness or a simple, set-and-forget head — the ST-Z or ST-X helps more.
Pros
- Outstanding workability — two sole tracks and two weights for any spin or bias a good player wants
- A fast, low-spin flight with one of the softest, quietest feels of its year
- One of the most premium-looking drivers on the market
Cons
- A compact better-player head — nowhere near the big game-improvement heads for stability off-centre
- Rewards a clean hitter — off-centre contact suffers, most of all with the weights set toward the face
- A niche, pricey, tinker-to-tune package
By dimension
Forgiveness
SolidNot its strength — a compact tour head that bites on heel and toe misses, more so with the weights set forward for spin.
Distance
StrongA low-spin bomber with a fast new face — the harder, lighter titanium adds ball speed across the whole hitting area.
Workability
ExcellentIts calling card — two long sole tracks and a pair of weights swing it from super-low spin to stable, and fade to draw.
Feel
ExcellentA soft, quiet strike — among the calmest, most refined impacts of its year, more a padded thump than a sharp crack.
Sound
ExcellentRemarkably hushed at impact — soft and understated where other heads crack and boom, which stronger players often prefer.
Looks at address
Class-leadingAbout as pretty as a driver gets — a small, tall-faced head whose glossy black top melts back into a carbon weave.
