Best for

Single-digit to mid handicaps (3-14) at 80-105 mph swing speeds who want blade-like aesthetics with PD-class forgiveness and best-in-class stopping power.

Avoid if

Distance-maxing buyers, or anyone who values the soft, muted feel of a fully forged players iron over the hotter hollow-body character.

Pros

Winner of 2021 Most Wanted Players Distance Iron — #1 in strokes-gained, tightest shot area, 2nd in yards from centre.
Higher launch + spin than competing players-distance peers — best-in-class stopping power.
Hollow body with Chromoly face + tungsten + copper underlayer = blade-looking head with PD-class forgiveness and feel.
Looks almost like a players iron at address despite the hollow construction.

Cons

Distance may not be its forte compared to other irons in the field — middle of the 2021 PD pack on raw distance.
Substantial mishits can still cost a club or two of carry distance — small misses are fine, big ones penalised.
Moderately loud snap with impact more fast than soft — hotter acoustic than a forged players iron, not for buyers wanting muted feel.

By dimension

Forgiveness

Independent robot testing 2021 Most Wanted Players Distance Iron WINNER — credited for highest average strokes-gained score, tightest average shot area, and 2nd in average yards from center. Hollow body construction with two 12g tungsten weights (toe + heel) in 2-7 iron lowers CG and improves stability. Reviewer testing qualifies: small mishits still hit the green; substantial mishits can still cost a club or two of carry distance. Class-leading PD consistency for 2021.

Distance

Editorial coverage: MP-20 HMB irons are quite long; similar distance results are comparable to the JPX919 Hot Metal. Hollow construction with Chromoly face + 32° 7-iron loft delivers PD-class ball speeds. Independent testing notes distance may not be its forte compared to other irons in the test — middle of the 2021 PD field on raw distance. Higher launch + spin profile than P790 — distance is moderate but consistent.

Workability

Reviewer testing: this is not a blade — not much offset, but the top line is substantially thicker than either of the other MP-20 models. Manufacturer: sharp tour-ready profile. Hollow body construction caps absolute workability vs the blade or MMC siblings — the head's larger footprint trades shape-shifting for forgiveness. Skilled players can flight it; not a true players iron for shape variety.

Feel

Manufacturer used a copper underlayer to improve feel on the MP-20 HMB — a feel-tuning material borrowed from the Tour line. Editorial coverage: the hit felt very soft yet also solid at the same time. Reviewer testing qualifies: moderately loud snap with impact more fast than soft. The Chromoly face + hollow construction produces a hot, players-distance feel character — softer than typical hollow PD irons but not as soft as a forged players iron.

Sound

Reviewer testing: moderately loud snap on centre with feedback that's quite clear even on mishits, which feel even firmer. Hot Chromoly face + hollow chamber produces a louder, more energetic acoustic than the forged blade or MMC siblings. Players-distance hollow-body acoustic — not the muted thud of a forged players iron, but cleaner than typical PD competitors.

Looks at address

Editorial coverage: at address, the HMBs look almost like a players iron, with the same shaping formula as the blade siblings. Reviewer testing: not much offset, but the top line is substantially thicker than either of the other MP-20 models. Editorial coverage: hollow body, but it looks like a blade in the bag. Premium players-distance silhouette that bridges the blade aesthetic with the hollow-body footprint.
