Re-reading Pat Dorsey's book on tailwater flies. His sort of signature fly is the Breadcrust - a fly he tied for many years in Colorado. He did not invent it, but took over tying them when the inventor retired from tying.
I added a little peacock hearl between the swept back grizzly hackle and the bead head.
I did not have ruffled grouse feathers, so used a wing feather from a Partridge.
Let me know what you think.
