I like the blue flies for big salmon and steelhead around this time of year (mid fall) and, wow, I really love that sweet looking blue grizzly hackle. This is a quick pattern and could easily be made a bit heavier for faster / deeper flows.
Jay Nicholas demonstrates how to tie a low water chinook salmon comet fly pattern. This simple fly utilizes traditional comet style techniques with Ice Dub for the body. The pattern is considered low water because it lacks bead chain or lead eyes. Eyes could be added to the pattern depending upon water clarity and depth.
