Specification comparison

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

Lofts compared

What the differences mean

At the 7-iron, the T100 is 34° and the T150 is 32°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the T150 should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the T100. Across the 8 clubs both sets share, the T150 averages 2° stronger, with the largest gap at the 3-iron (21° vs 19°). The pitching wedges are 46° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.

The sets are built differently: the T100 runs 3-iron to W (9 clubs), the T150 3-iron to GW (9 clubs).

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 T100 is listed as forged, multi-material and the T150 as forged, multi-material dual cavity. Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.

There are 4 years between these sets (2019 and 2023), more than one design generation. Over that time irons moved toward stronger lofts, thinner and faster faces, hollow and multi-material heads and wider use of tungsten, so the newer set is not simply a better version of the older one: it may launch and spin quite differently. Here the 7-iron loft moved from 34° to 32°.

Which should you choose?

The T150 is the stronger-lofted set — up to 2° stronger than the T100 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
