Performance index
Six researched ratings, lower (blue) through to elite (gold).
Where it wins
- Looks93
- Feel90
- Workability88
Watch
Rated highest for looks and feel; its softest dimension is forgiveness.
Single-digit handicaps (3-12) at 85-110 mph swing speeds who want tour-input refinement of the Pro 223 players-cavity benchmark with class-leading sole geometry.
Mid-to-high handicaps (10+), or tour-blade purists who want a fully forged construction throughout the set (look at Pro 241 instead).
Pros
- 2025 Golf Digest Hot List Gold Award (Players Irons) — Top 5 in Performance for low-handicaps.
- Forgiveness on offer is certainly an improvement compared to previous iterations, and a touch better than other 2024 competitors.
- Shaft-optimizer-data-driven sole with beveled leading edge + relief on trailing edge — meaningful turf-interaction upgrade.
- Copper underlay produces muscle-back, blade-like feel in a players-cavity package.
Cons
- Have to be a confident ball-striker who is in the low single figures to get the most from them — narrow fitting window.
- Incremental refinement vs predecessor rather than a generational breakthrough.
- Chromoly face firms up the impact in 4-7 irons vs the all-forged scoring irons — feel transition through the set.
By dimension
Forgiveness
ModestEditorial coverage: forgiveness on offer is certainly an improvement compared to previous iterations, and a touch better than other competitors in 2024. Same Chromoly + Micro-Slot face in 4-7 irons as predecessor. Reviewer testing: the thinner face did produce a small bump in ball speed compared to the muscleback sibling — modest off-centre help. Industry tester: covered up all my errors, which is kind of unheard of in a players iron. Slight improvement over predecessor — still strike-dependent for the players-cavity category.
Distance
ExcellentReviewer testing: high ball speeds and mid spin for those single digit handicaps. Same Chromoly + Micro-Slot face construction as predecessor. Editorial coverage: ball speeds for the longer irons were higher than expected but remained consistent, with mid to high launch and relatively low spin. Same 32° 7-iron loft. Same caliber as predecessor.
Workability
ExcellentIndustry awards: split cavity-muscle design with a thin topline and compact head shape. Reviewer testing: looks of a player's iron without the demands of a true blade. Compact players-cavity silhouette + 32° 7-iron loft + neutral CG = elite shape-shifting iron for skilled players. Same caliber as predecessor with refined geometry.
Feel
Class-leadingIndustry awards: copper underlay for a muscle-back, blade-like feel. Same Grain Flow Forged 1025E in 8-PW + Chromoly 4-7 construction + copper underlay as predecessor. Reviewer testing: iconic forged feel in a players cavity back iron. Step up from predecessor's already-strong baseline via tour-input refinements on weight placement.
Sound
ExcellentSame Grain Flow Forged 1025E in 8-PW + Chromoly 4-7 + copper underlay construction as predecessor. Editorial coverage: pleasing acoustic from the tour-input refined cavity design. Same caliber as predecessor — refined acoustic in a players-cavity package.
Looks at address
Class-leadingIndustry awards: thin topline and compact head shape. Editorial coverage: refined compact players-cavity silhouette via shaft-optimizer-data design. Reviewer testing: looks of a player's iron. Premium players-cavity aesthetic refined from predecessor — marginal uplift via thinner topline and tour-input shaping.
