Ah fair enough, I kind of thought that the 2x might be the root of the problem. The only other derailleur I have would not manage the size of the large sprockets in the cassette so I guess I’ll live with it.
It shifts pretty well with the shifter in friction mode, and the indexing is a bit better too now that I’ve given the hanger a little attention.
Edit: I've also slid the wheel forward in the dropouts to simulate a slightly longer chain and definitely runs better as it was.
