Here we are....

IG chains for XTR with HG cassette and Hyperdrive C chainset
Same for XT, which also had HG chainset.
And the evidence.....
When I started using my Parkpre with M950 chainset and HG91 chain it worked fine.
When I found a source of NOS IG-90 chains (there still seem to be plenty available btw., shameless ad!), I swapped the HG91 out. No change to rear shifting but the front shifting did seem to improve a notch and there seemed to be less chain noise in the extreme middle ring combos. (placebo effect cannot be ruled out though- it was a non-objective test).
So IG is indeed, as I remembered, all about front shifts, not rears. They just happened to also make some low-end IG cassettes for a while. But IG will shift fine on HG.
