Margulis begins one of his articles by posing the 
question, "How much USM to use?"  And his answer is -- 
it's like asking for a raise.  IOW: as much as you 
can get away with.

I must admit, some of Margulis' USM techniques go 
way over my head.  In the article I saw, he elaborates 
it into a multi-step process involving several layers, 
color spaces, and layer-merging steps.

When it comes to sharpening, there are many ways 
to skin the cat.  Quite of few of these have been 
discussed on the Leben Epson list as well.
