Quote - What I'm becoming increasingly aware of here is that one size just might not fit all.

Lol ain't that the truth. That to me is one of the coolest things about this thread. We can debate the preffered pros and cons of different methods. In the end there really just suggested preferences. Any method has strengths and weaknesses. I do hope you reconsider the lip/chin
split. I would prefer that stitched more so than the upper/lower body. As you say though Im sure if some do not prefer your layout they can make thier own. Myself I hate uv mapping because of the balance between minimizing distortion and making it seam friendly is a nearly  impossible task. I would love to make some morphs for her. That atleast Im pretty decent at. ;)
