In this video, Simon ties a foam body Grey Drake Dun which works great in the fall when these larger mayflies come off. The abdomen is made of 2mm foam instead of being dubbed to reduce water absorption which greatly improves buoyancy. The fly is tied with water wicking fibers, and hackled vertically which allows it to shed water quickly with a few false casts. The vertical hackle can be trimmed horizontally on the water with nippers creating a lower riding fly for the pickiest of fish. Size and colors can be swapped to mimic other mayflies depending on the season or your local fishery. Fish it and let us know what you think!
