The thing I like about the INJ system is that you could load only the morphs you needed.  That was kind of the point, I thought.  Figures could come pre-loaded with all their morphs, but then you bog down your system for stuff you're not even using. 

I gather with DSON, you once again end up carrying all the morphs.  Does it work that way in DS, too?  Or is this just a Poser/DSON issue?
