Cage, I had a look at your modified JPs. Thanks again for sharing those!

They seem to help in some situations, but not others. So I think I'll stick with the existing JPs by default, after all, which stretch the neck more evenly overall. But I think it would be very useful to make your JP modifications available as pose files, so that if someone comes across this problem, they'd have a choice of workarounds. So I'd like to include some or all of your pose files in the official distribution, if I may.

I think it would also be interesting to look into scale-controlled morphs for the neck and maybe some other limbs at some point. They have problems as well, particularly the shading artifacts I noticed when I tried using them with non-smooth scaling, but maybe in this case they will behave reasonably well.

-- I'm not mad at you, just Westphalian.
