All interesting and worthy fly variations posted....

Following is a link to a site showing many Steelhead flies, the Bomber -Tri,
in various colors is the type of skater/waker that I have used.

In regards to the Muddler, I've had very good luck fishing the fly dry
(primarily during an October caddis hatch when I have ran out of orange
stimulators) , I have never run in sub-surface... Might give it a shot
through some deep holes sometime...

Thanks,
