The demon midge was designed by one of colorado's top fly fishing guides. He goes by the name of Matt McCannel. He is the head guide for Rig's Fly Shop in Ridgway, Colorado. Matt is a true tailwater assasin with his expansive knowledge and years of guiding. His demon midge is extremely effective on tailwaters where trout have a PHD in flies and presentation. Matt can be found sighting fish from a ladder for his clients on the tailwaters of The Uncompahgre River. Add this pattern to your midge box. You won't be sorry. You will receive one half dozen flies with your purchase in size 22. These flies are tied to order.
