The reason many of us use different approaches to sharpening is because many
images do not do well with USM, even though we are fully aware of how to use
it.  My own personal opinion is that your threshold settings are too high...
but again, that's my opinion. With threshold settings higher than your
radius settings you are conteracting the radius thus making the image soft
again.

I've personally never maligned USM, it has many great uses. But to use it
with other techniques makes it all the better at times.

I've used all of Bruce's techniques with great success over the years, and a
few of my own. But find that many of the newer techniques I've run across to
be just as successful... and lead to development of more of my own
techniques.  It's all good.
