Because of what Vilters said an investment in V4 content I have been digging around in the V4 CR2.  (I very much like (as with Dawn) being able to drive all bends and morphs from BODY and I am stuck once again doing methods research.)

Am I correct in thinking? =

the actor body Morphs section and link parms sections are DS components only? Can be deleted with no effect on the figure in Poser?

With V4WM - no V4.2++ JCM or magnets are needed (The 3 pairs of breast magnets may be worth keeping.)?

Is the PoserPlace V4WM conversion different from AlfaSeed conversion?  When WM converted, V4 is just as modern as any other figure in Poser?

One other aspect of V4 content though - with the functions in PP2014 -  Texture Converter (Blacksmith)  and Netherworks Hair conversion - much of V4 can be adapted to Dawn and Roxie  - and excluding textures most any other figure.
