This is a bit OT, but associated with some of Vilters comments.  I find it easier to morph something larger than smaller.   I am thinking that a base female figure should start with a flat chest (AAA or whatever)  with an abundance of polys to support very large shapes.  Since the base figure is essentially just one version a morph, there is nothing to stop the figure's vendor from having a morph set that produces B/C/D breast sizes in the advertizing copy.

I also agree with the proposition that the arangement of the polys should outline the position of all major muscle groups, tendons, surface bones.  If you want to morph a larger calf muscle or prominant ribs, you should not have to guess which polys to choose.
