I've been using the V4wm, haven't tried a waist bend like that, but sometimes with certain arm positions I still get some tiny imperfections.  Usually the morph tool set on smooth is enough to blend out any small ripples very nicely.

I used Antonia too!  I'm going to get PhilC's wardrobe converter plug ins so I can give her more clothes selection.

I have to say, overall, the WM characters are so nice to use.  I'm blown away by the communities efforts and extremely thankful as a user.
