tricks big nasty trout!
You really can't beat a comparadun, unless it's a cdc comparadun. If you fishing slow slicks with super selective trout this fly is probably your best option. Sits low in the water and the cdc looks even more realistic than hair. For best results, I'd recommend not applying gink (gel type floatant) to the feather. It will work, but it makes the cdc clump together. I have found that if you use a dry powder such as frogs fanny, it leaves the feather looking much more natural. This holds true to all dry flies that use cdc. I do apply some gink to the biot body though.
