If you take a look at La Femme for instance, that figure was designed with Poser Subdivision in mind. It's a low medium mesh. In my eyes more medium. I haven't looked extensively at Blackhearted's HD morphs but from an initial look at his new HD morphs for the Anime girl set I'm seeing morphs intended for 1 or maybe 2 levels of subdivision. I'll have to look closer but I don't think anyone has truly done any high frequency stuff with figures and subdivision in Poser. It's just not practical. Because of this having a low poly figure with the expectation to "fix and add/detail" with subdivision seems shortsighted. Strictly from a user friendliness standpoint. You lock out content creators from morphing options at the base resolution and the subdivision burden is too great on a Poser scene to truly take advantage of the functionality. Probably best to build at medium resolution for the most flexible user experience, at this point hardly anyone is going to be adding more than 2 levels of subdivision in a typical Poser scene with dense hair models and props and scenery. It's a bog.
