This version of the CDC Choronimid has been with me for close to 25 years. It began tied for Northwest lakes using a red thread body and a peacock herl thorax. While that version still catches fish, this is the current version that has been in my box for more than 10 years now. It is my favorite and most productive Choronimid pattern by far.
