I was pretty pleased with the fly and how well it fished. Great baitfish pattern for sure. My only complaint was the amout of wasted material from trimming and sculpting the shape. The material just seem to mound up and scream at me 'don't throw me away'. Now it doesn't take a lot of prompting to get me to save material. My friends refer to my trash bag as a holding bin instead of a trash container.
So I bagged it up and stuck it away. It's rolled around to sulfur season and Comparaduns are the focus on the bench. I don't tie my mayflies with adult tails but more often tie them with a 'tailing shuck'. Tied a few with poly yarn and remembered that scrap from earlier in the summer.
EP fiber and similar products I have found out from tying and subsequent fishing make excellent trailing shucks. So I strongly suggest that you save those fibers.
I am planning on chopping some up and adding to some home blended dubbing.
