thanks again Joe...

ill try converting to WM before adding the bone , this may be the answer, i was using the standard falloff zones before and i can see where adding additional zones may crowd existing zones...perhaps forcing sharing of verts between existing and new zones?... would be nice to simply inject new features without having to overwrite existing, I'd like to enhance without detracting from work thats already been done if possible...

very nice bend you have there Joe

Y'all have a great day.
