Always wanted to do a one fly contest. I would use a beadhead copperjohn with 3X. I usually use light tippet and bust off a bunch of flies during the course of the day. Heck, I've had days when one rod wasn't enoungh. Bro Ken (Lurker) would be using a Adams. I just changed my mind. I would use a big hopper. May not catch as many, but I never lost a hopper and have caught my biggest trout on em. Wish I could join in the fun. Good Luck to everyone and let us know the results.
