Last season at the Edison Flyfishing show, I saw a young tyer tying quick and easy flies. It was the wing material that caught my eye. up/dn trout, wings for insects. As a guide I want quick during the season, seeing this synthetic wing material and how it was used I thought what the heck buy a bag. I am so pleased I did, it makes Great compara dun wings! It floats great and is durable. I can see it on the water no matter the light conditions. For small flies #18 and down I can cut the material in half for size. I really like it for blue wing olives! CDC is great but you need to powder it during use at times, Deer hair is buoyant but eventually you start losing hair, this synthetic material just last. So if you visit the show this year grab a bag, try it I think you will be surprised. Bottom photo's showing the material, if you like darker wings use a marker to the color you desire.
