I myself gravitated away from V4 mainly due to the nightmare that is developing any FBM for her, as you're forced to morph each body part separately while respecting the seams so you end up saving a bunch of separate pieces instead of the freedom of doing an FBM with the figure intact, and with the added benefit of stretching/growing/shinking the limbs without concerns for the rigging as they can easily be fitted to your character!

So yeah, I have a love/despise relationship with V4 and the rest of the 4th generation of Daz characters, sure I had fun with her but that was because there was nothing else!
