The Stick figures and Mannequin were originally created so as to create poses that wouldn't affect the 'Body Sculpting' morphs.  Angleoucuitry's suggestion would probably work too, but to be safe I believe it's best to pose a figure that has absolutely NO morph channels whatsoever.
BTW, this suggestion isn't originally mine, but one I picked up from reading the old forum archieves -those that date back to 1999. 
There is a lot of information stored in those old archieves, the developement of Eve by Torino, the controversy over the first Vicky (more than a few thought that she was 'Butt Ugly', a sentiment to be echoed later over Judy), and various other situations.  In short, it pays to dig and delve.

PS: One of the benefits of MY suggestion, is that you won't have to redo any dial twirling on your own custom created figure after applying a pose.  After having worked all day on a customised figure, save it FIRST as a Pz3, thin load the mennequin and apply pose, resave pose, and then apply to Pz3 figure.  This way, if you've made a mistake, you can reimport your work without any significant loss.
As in any customised work: SAVE, RESAVE, & SAVE AGAIN!!!!
