Ahh! nice…
I would have solved that with Follower: pasting it in all bones and changing the + signal to - signal on half of them. But that expression thing its new to me.

If you had some 20 bones to do that, just had to select them bring them to graph editor, Heading channels Filter, select and apply the expression for each positive and negative group, right?

Correct. It goes pretty fast.
