What the differences mean
At the 7-iron, the T100S is 32° and the T100 (2021) is 34°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the T100S should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the T100 (2021). Across the 9 clubs both sets share, the T100 (2021) averages 2° weaker, with the largest gap at the 3-iron (19° vs 21°). The pitching wedges are 44° and 46°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.
Both are players irons, built for roughly scratch to 10 handicaps. Small-to-mid cavity backs with traditional lofts, modest offset and workable shaping for low-handicap players. 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 T100S is listed as forged, multi-material dual cavity and the T100 (2021) as forged dual cavity, multi-material. Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
The T100 (2021) came out 1 year after the T100S, 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 T100 (2021) is the weaker-lofted set — up to 2° weaker than the T100S. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
