I was recently challenged with converting the collors associated with the famous Atlantic salmon streamer known as the magog smelt into a swingable spey like fly. I use this termonology very loosley, since you can certainly swing a magog smelt.

When I got toward the front of the hook, I added and extra patch of the white to the bottom side of the hook. Again a teal flank collar, some synthetic flash underwing, and some peacock for a topping. I then added some Flymen Fishing Company Living Eyes secured by some Clear Cure Goo. I had a keeper in my mind! I played around replacing peacock with synthetics and was indifferent in my opinion.
