It's true that smoothing can make Posette look better, but she still looks like Posette. Some artists use Poser figures to get a likeness - of clients, family members, celebrities, politicians, or just the man or woman of their dreams. That's where V3's easy morphability shines.

The INJ/REM system is meant to make V3 lighter on the system resources. You can inject only the morphs you want, and leave out the others. And you can add or remove morphs at any stage, if you find you need a morph you didn't think you'd need.

It is easier to just load everything up; that's what I usually do. When you're done, you can remove the unneeded morphs. There's a little program by NeilP in Free Stuff that deletes unused morphs from V3.

V3 isn't my favorite female figure; I prefer Stephanie Petite. But I probably use V3 the most, because she's got the most stuff. That counts for a lot, I think.
