Thanks for the pattern . Bear. Very cool. The fellow that I saw using them, I've seen numerous times, as he's a long term resident of Altmar and fishes a lot. He told me they weren't something he uses regularly, being a pain to collect. A friend had given him some, so he gladly used them. Once again, I have to plead ignorance, I'm just relating an observation.
I recently tied a bunch of Mike Mercer's dark poxy back stones for a friend to use on the Trinity in California in size 6 and they worked well. That river has many similarities with the SR. Those are a Skwala stone though, not a Dobson. I tied a bunch for myself, too. I have fun knowing jack squat about fisheries sometimes, and just winging it. I've spent a bunch of time on the water teaching people to fly fish, sometimes that carries over and I say way too much . I'm very much an outsider here, with little knowledge, so I'll go back to being quiet.
