Just being conversational (about boobs) but I've found that musculature, and the sort of natural cleavage effect in certain women's physiology build (as seen in the picture of Emily Ratajkowski below as a good example), and also demonstrated by Posermatic's classic Natural Gravity Morphs for V4, is best served by this redirection of edgeflow. Much better than the plain strip of thin polys (that often pinch from compression) shown in LF and Dawn. I recall trying to point this out about Dawn 2's topology previews at HW forums and met with counter images of D2's boobs inflated and pressed together in a typical Poser manner. I didn't bother arguing further the point. Also, if you are familiar at all with Posermatic's NGMs they demonstrate a very natural appearing  extreme pendulous breast variety not often seen in other Poser figures! It's my assertion that this sort of topology is most conducive to this ponderously pendulous quality!

Anyway, sorry for the OT, woolgathering and meandering and whatnot ;)
