Highlighted cells differ between the two sets. Lofts and lies are factory standard.
Lofts compared
- Deep Red
- Staff Di7
What the differences mean
At the 7-iron, the Deep Red is 32° and the Staff Di7 is 31.5°, a 0.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Staff Di7 should carry about 2 yards further with that club, on a slightly lower, shallower flight than the Deep Red. Across the 10 clubs both sets share, the Staff Di7 averages 0.5° stronger, with the largest gap at the 8-iron (36° vs 35°). The pitching wedges are 44° and 43°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Deep Red runs 1-iron to LW (13 clubs), the Staff Di7 3-iron to SW (10 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.
The Deep Red is listed as cast cavity back and the Staff Di7 as cast undercut cavity. 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.
There are 4 years between these sets (2002 and 2006), 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 32° to 31.5°.
Which should you choose?
The Staff Di7 is the stronger-lofted set — up to 1° stronger than the Deep Red on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Wilson Deep Red stronger lofted than the Staff Di7?
No. The Staff Di7 is the stronger-lofted set: its 7-iron is 31.5° against 32° for the Wilson Deep Red, 0.5° stronger and worth about 2 yards of extra carry.
What is the loft difference between the Wilson Deep Red and Staff Di7?
At the 7-iron the difference is 0.5° (32° vs 31.5°). The largest gap on a shared club is 1° at the 8-iron, and 6 of the 10 shared clubs differ.
Are the Wilson Deep Red and Staff Di7 aimed at the same golfer?
Yes. Both are game improvement irons, built for roughly 10 to 25 handicaps. Choose on feel, looks and gapping, ideally after hitting both.
Do the Wilson Deep Red and Staff Di7 have the same lie and length?
At the 7-iron, yes: both are 62° lie and 37.5 inches long.
