Teyon,
You are right.

With a WM, you do not "NEED" JCM's.

Before WM, I made tons of morphs to get bends and movements right.

Now with WM, I deleted most of those, and I have not created a single one since I got PP2012.

In retrospect?
It would have been a lot smarter to just deleted ALL JCM's, before going to WM.
