What the differences mean
At the 7-iron, the Staff Di9 is 32° and the Staff Di11 is 32°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 10 clubs both sets share, the differences roughly cancel out, with the largest gap at the GW (49.5° vs 46°). The pitching wedges are 42.5° and 43°; the stronger one leaves a 7.5° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Staff Di9 runs 3-iron to SW (11 clubs), the Staff Di11 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.
Both heads are listed as cast cavity back. 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 Di11 arrived 2 years after the Staff Di9, 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.
Which should you choose?
The Staff Di11 is the weaker-lofted set — up to 3.5° weaker than the Staff Di9. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
