Highlighted cells differ between the two sets. Lofts and lies are factory standard.

Lofts compared

Lofts match on every club the two sets share, so the markers sit on top of each other.

What the differences mean

Every club the two sets share has exactly the same loft, starting with a 31° 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 game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. 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 S3 is listed as investment cast multi-material and the AMP as investment cast multi-material cavity back with a full-cavity urethane layer. 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 AMP came out 1 year after the S3, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.

Which should you choose?

The S3 and AMP share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
