You can pick up the Autofit right now for like $5 in magazines.  Grab it, grab free DS4 and give it a whirl.  Why not?  On some of your outfits, it will spek for itself, both good and bad.

Also, don't get confused with the ease of "morphing" genesis, versus "blending" your purchased morphs.  It is great at the latter.  You still need to purchase morphs for Genesis.  (i.e. V4/M4 shapes, Troll, Creatures, etc...)

So you'll still need to purchase morphs, but once you have them, you can dial in 20% troll, 30% david and 40% V4....to make whatever that is?
