No blotches, but on the other hand no polygon smoothing.  I have my settings so tuned to try to avoid the blotch problem that likely I am losing almost all occlusion shadows, I'll tinker a bit and see if I can get more out of that.  I'm not all that enthusiastic about this as a fix because I really want to use polygon smoothing - even though this is a high poly item here, it still shows poly lines more than I like.
