Yes, I did appreciate the discussion, and I picked up a few things, though 
none of it really had to do with my original question, which was how might 
people be using Silverfast's USM feature in combination with Photoshop's.  
In my own experimentation, Silverfast USM intensity of 80-120 and threshold 
of 2.0-4.0 seems to find the edges pretty well, but it can end up being too 
much sharpening to permit any further refinement in Photoshop.  Much less 
sharpening than this in Silverfast, and it is difficult to see in the 
preview.  I think that the Silverfast preview for USM simply doesn't work 
very well.

My conclusion is to do as you originally suggested (whether for the same 
reason or not) and just not use USM in Silverfast and do it all, whether 
once or twice, in Photoshop.
