I’m crazy about CDC, and it’s kind of a weird material to be enamored with since it comes from a duck’s ass and all. But I love it for lots of applications, most importantly, realistic wings that hold a dry fly right in the film where fish are most likely to take a swipe at it. This pattern from “The Feather Bender” is a great traditional-style green drake from across the pond that will surely take fish on the rivers of western Montana. Lots of green drake patterns these days are flashy and loud, and I get the sentiment of the tyer: A big mayfly is the prefect chance to show off a little. But the reality is these bugs are often in the ugly slow water, where silt-bottoms allow their nymphs to get chunky and hatch. The bugs aren’t so much flashy as they are bland. But fish love them, and I have a feeling some of these would do nicely in your box this season. It’s a chance to use some of that lovely CDC you’ve got, and your custom dubbing blend you know you want to bust out.
