Fascinating post Torrey, I'm interesting in hearing your thoughts?!
I'm going through the fly selection chapter in the Supinski right now, so I'll be better versed within the next day or so.
As for me, right now at the moment, I'm tying some hot-pink C.J's., as it is a favorite of Barr's for Steelhead fishing. I'm also trying to get a good number of Stones tied up before the next trip up to the SR (which will hopefully be soon).
We had a great post going a week or so ago about "Nymphs and Hot-spots" which covered a lot of Steelhead questions of mine. In there you outline a few stone patterns/variations with hot-spots to create a more "vibrant" version. I remember a crystal stone that sounded really interesting.
