Pro 225
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
Single-digit to mid handicaps (3-15) at 80-105 mph swing speeds who want hollow-body players-distance forgiveness in a more compact, refined silhouette than the MP-20 HMB.
Buyers who want maximum forgiveness (look at game-improvement irons) or pure forged feel (look at Pro 221 / 223 siblings).
Pros
- Winner of 2022 Most Wanted Players Distance Iron robot test (97.53/100 overall).
- New CORTech multi-thickness face delivers quicker ball speeds than the predecessor.
- More distance, softer feel, and the ability to hold greens with more regularity vs the predecessor.
- More compact tour-ready hollow-body silhouette — second-generation Hot Metal Blade refinement.
Cons
- Forgiveness dropped to 5th in 2022 PD test vs predecessor's #1 strokes-gained crown — trade-off for the tighter compact silhouette.
- Hollow body acoustic still firmer than the forged-blade Pro family siblings.
- 30° 7-iron loft + low-launch geometry trails the players-distance feel benchmark of the cavity-back sibling.
By dimension
Forgiveness
Independent robot testing: 2022 Most Wanted Players Distance WINNER — total score 97.53/100, 5th-place finish for forgiveness with score 86.66/100, and 2nd-place finish for accuracy. 28.5g of tungsten positioned low and deep in 2-7 iron (vs predecessor's 24g split between toe + heel) — repositioned mass for higher MOI. 4135 Chromoly hollow body construction carries over from predecessor heritage but more compact. Slight regression in pure forgiveness vs predecessor's #1 strokes-gained crown — the trade-off for the tighter players-iron silhouette.
Distance
Independent robot testing: third-place finish and a score of 92.73 for distance in 2022 PD. New CORTech multi-thickness face delivers quicker ball speeds vs the predecessor. 7-iron loft 30° (2° stronger than predecessor). Manufacturer: faster ball speeds than the predecessor. Meaningful distance gain.
Workability
Editorial coverage: more compact than the predecessor. Hollow body construction with tour-ready compact silhouette + 30° 7-iron loft — still a players-distance iron, not a true players blade. Tungsten low-and-deep CG produces neutral trajectory bias. Improvement over predecessor due to tighter silhouette and refined CG positioning.
Feel
Editorial coverage: more distance, softer feel, and the ability to hold greens with more regularity vs the predecessor. 4135 Chromoly forged hollow body with refined construction. Independent robot testing highlighted distance, accuracy and feel as the three drivers of the #1 finish. Improvement over predecessor's hot players-distance feel — softer and more refined.
Sound
Hollow body construction with 4135 Chromoly produces a more refined acoustic than the predecessor's louder snap — editorial coverage notes the softer impact character translates to a tighter acoustic. Editorial coverage: improved refinement vs predecessor without losing the players-distance character. Better than predecessor baseline but still below the forged-blade benchmark.
Looks at address
Editorial coverage: more compact than the predecessor — tour-ready hollow-body silhouette refined for the Pro family aesthetic. Manufacturer positions the iron as second generation of the Hot Metal Blade — preserves the blade-look-with-tech-inside philosophy. Marginal aesthetic uplift vs predecessor's already strong silhouette.
