What the differences mean
Every club the two sets share has exactly the same loft, starting with a 34° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show.
Both are blade irons, built for low single-digit handicaps who strike the ball consistently. Compact muscleback irons with minimal offset, thin toplines and the smallest sweet spot — built for shot-shaping over forgiveness. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The MP-20 MB is listed as forged and the Pro 221 as Grain Flow Forged HD. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The Pro 221 arrived 2 years after the MP-20 MB, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The MP-20 MB and Pro 221 share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
