Shane Stalcup’s CDC Biot Trico Comparadun is my favorite Trico imitation. It can be fished as a dun, spinner, or drown spinner imitation. I typically tie it in sizes 20-24 to match the Trico hatches that occur throughout the Western United States.
Here is the recipe, tie a few up, you’ll be happy you did!
