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

Lofts compared

What the differences mean

At the 7-iron, the Staff D7 is 28° and the Staff D9 is 27°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Staff D9 should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the Staff D7. Across the 7 clubs both sets share, the Staff D9 averages 1° stronger, with the largest gap at the 5-iron (22° vs 21°). The pitching wedges are 43° and 42°; the stronger one leaves a 8° jump to a 50° gap wedge, which matters when planning wedge gapping.

The sets are built differently: the Staff D7 runs 5-iron to GW (7 clubs), the Staff D9 4-iron to SW (9 clubs).

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.

Both heads are listed as investment cast. 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 Staff D9 arrived 2 years after the Staff D7, 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. Here the 7-iron loft moved from 28° to 27°.

Which should you choose?

The Staff D9 is the stronger-lofted set — up to 1° stronger than the Staff D7 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
