Willie Gunn Friggi Copper Tube is designed with movement in mind. The design is new for this season and will give you an advantage when fishing this new profile fly. I believe that the profile of your fly is very important and showing them something fresh and also something they have not seen before can only be an advantage to try and induce a take. The Willie Gunn Friggi Salmon fly is designed to swing through the streams showing the fish a duel wing.
