Where it wins
- Looks88
- Feel82
- Sound78
Watch
Rated highest for looks and feel; its softest dimension is workability.
You slice or push the ball and want an easy, high launch with a lovely feel from the middle.
You strike it inconsistently and need real forgiveness, or you want to shape shots or work a fade.
Pros
- A subtle, modern draw bias that fights a miss right without looking like a draw driver
- A superb feel and fast, forged face on a centred strike
- A big, friendly, square-faced look and an easy high launch
Cons
- Forgiveness is a weak point — high and low face strikes wander
- Mishits feel hollow and sound harsh
- Five seasons old, with a fixed draw and no adjustable weights
By dimension
Forgiveness
FairIts weak spot — the heel weight lends some stability, but strikes high or low on the face see launch and spin wander.
Distance
StrongA fast, forged beta-titanium face brings real ball speed, with a high flight and only moderate spin.
Workability
ModestA fixed draw head — the heel weighting nudges the ball right-to-left, with little scope to shape or fade it.
Feel
ExcellentExcellent off the centre — a dense, lively strike that feels genuinely powerful, though a mishit goes noticeably empty.
Sound
StrongHushed and mid-toned on a pure strike, but a miss speaks up sharply and less sweetly.
Looks at address
ExcellentYou'd never guess it's a draw head — a large, broad shape with a square face that sits assured and tempting behind the ball.
