Honestly said, I don't "believe" in additional "helper bones" in a rig.

I rather use a JCM instead. Much more accurate and a morph much less likely will cause problems along the road than additional bodyparts can do.

thanks for responding Joe

i understand what you are saying about accuracy, i wish to try applying Jcm after making a new bone , using the new bone to drag verts into rough alignment, thinking it may save a morph or 3, as you well know these verts want to follow the straitest path to their targets requiring multiple targets to round a bend,  perhaps a new bone may lighten the overall load of the figure... im not sure but, i have time and patience to test these assumptions.

:O)

Y'all have a great day.
