Quote - Poserpro 2012 needs more density for hairgroups compaired to older versions.

Well, not quite.

What requires more density is if you lower the default root and tip widths (which are clunky thick). Naturally, if each strand is thinner, you will need more strands in order to get to the same overall "thickness."

Re retaining a style after draping: root stiffness will affect that, but theoretically at least, mostly at the roots. For general retention, Position Force would be the more apt setting to turn to. There other settings having to do with resistance to bending etc too that will play in here.
