Where it wins
- Feel90
- Looks88
- Workability86
Watch
Rated highest for feel and looks; its softest dimension is forgiveness.
You're a low-handicap, skilled ball striker who wants a buttery-soft forged blade with maximum shot control - the ability to flight and shape every iron shot.
You need forgiveness, easy launch or extra distance - any player who doesn't strike it consistently from the centre.
Pros
- Possibly the softest-feeling iron ever - a one-piece forged 8620 carbon steel muscle-back
- Maximum shot control - it flights the ball high or low and bends it left or right in spades, in the right hands
- A little more playable than a typical blade - it lets you get away with some poor swings
- 8620 carbon steel for better durability and longer groove life
Cons
- A muscle-back blade - maximum control at the expense of forgiveness, for skilled players only
- Traditional lofts and blade distance - not a distance iron
- A premium price
By dimension
Forgiveness
ModestA blade, but a kind one - a muscle-back that targets skilled golfers wanting maximum control at the expense of some forgiveness, yet a little more playable than expected, letting you get away with some poor swings, on a solid 8620 carbon-steel body with no cavity technology. Low forgiveness, if gentler than a typical blade.
Distance
SolidControl over distance - a blade built to control distance and trajectory rather than chase ball speed, with traditional blade lengths, the solid forged body prioritising feel and control over the hollow-body distance of the other Gen4 models. Short by modern standards, by design.
Workability
ExcellentControl in spades - precise control over ball flight in spades, flighting the ball high or low and bending it left or right in the right hands, a Tour-inspired geometry for maximum control over distance, trajectory and shot shape. Elite, blade-grade workability.
Feel
Class-leadingPossibly the softest ever - the Gen4 0311 ST irons might be the softest ever hit, a buttery, pure forged feel from the 8620 carbon steel. Elite, blade-grade feel.
Sound
ExcellentSoft and muted - a soft, muted click off the forged blade, a quiet, premium note. A refined, soft acoustic befitting the soft feel.
Looks at address
ExcellentClassic blade beauty - a clean, compact muscle-back shape with thin top line and minimal offset, a premium Gen4 finish. One of the best-looking better-player irons of its era.
