Want we should start a discussion on this sometime, dlfurman? I'm also a paper-and-pencil pusher, basically lousy although I did once study artist's anatomy in college. I've experimented a bit with using Poser to rough out a pose. So far I've just been developing linework, but I'd also like to try using Poser to figure out some of the shadow planes. Even with this limited experience I found Poser was best at giving me the overall silhouette and the general position of some of the landmarks. All the actual detail, esp stuff like clavicles and nucheal notch, shoulder blades, rib margin, I drew for myself, not even attempting to follow the model. So at this point I see the possiblities of a god muscle map, but I would personally make only light reference to it, adjusting by eye and book for anything important.
