It really is the "newest thing since sliced bread," simply because the bending you speak of is immensly different that what we are use to. 

I'd suggest you go grab the free V4WM and/or Antonia WM at RDNA and see for yourself.  Prepare to be thrilled.

And, while you're there, grab the Outfitter.  This is a python script for converting your existing clothing to weight mapped version.
