Thanks again for your thoughts, Les!

My take on this is that hands don't really twist. There's a perfectly functional forearm twist, and all I could achieve by this change would be a duplication of that. I think that little bit of extra convenience for the user is probably not worth redoing the wrist JCMs and risking further problems with the hand rigging. If this leads to confusion, maybe I could just hide the dial for the hand twist?
