Well, I kept at it. I got it to low brace, took a little off, tried again, took a little more off trying to get it evened out. Eventually took it to 35# at 27".
Seems like there's still a little bit of hinge close in on the right, and the left limb is still too stiff, but it feels like it's getting closer.
Also looks like it's taken a little bit of set. Hm. I think I can live with that much.
Maybe tomorrow night I'll try full brace, and see if I can't get it evened out. If it's only pulling 35# at 27" though, I'm thinking I won't get much more than that at 30", by the time I have it all evened out.
