While I no longer use Poser, I do have one bright spot that I discovered in all of this (oddly enough, with D|S). I held out against using Genesis, mostly because I had a mountain of V4 stuff. Then, they came out with V4 for Genesis... it was like seeing your girlfriend's boobs for the first time. All of the V4 stuff I owned just fit - and no need to push and pull to get it to fit anymore - it just did, even on custom G2F meshes. ...at least in my case, that was the perfect solution. 

Now for Poser? I don't know if Poser has anything similar, but you can at least use D|S to get the G2F figure fleshed-out and clothed, then export to Poser to do what you will after that.

Not trying to bash D/S here, but this is where the whole workflow argument falls apart for me. My goal is to reduce my workflow, not increase it. So adding another software in the mix just goes against the grain for me. I'd rather just use V4 or V4WM. I get to use all my V4 stuff and my favorite software and I don't have to jump through 24 other hoops to do it.
