There is a fly I feel very uncomfortable being on the river without. This fly is the CDC & Elk.
Thinking back over the last 10 years, fly hatches in general have become a little chaotic and more and more unreliable on our rivers, however, I’m happy to trust the pulling power of the CDC & Elk. This pattern is fantastic for both searching and targeting rising fish, and can be used to imitate the sedge (naturally) or even larger upwings such as Large Brook Duns. Fish this on a smaller upland stream and you may not need another fly all day!
