I do not feel I am qualified to respond on this fly you have tied, but, I like it and feel that the only thing I would add, if I had tied it, would be that I would have tied 4 or 5 peacock herls on top over the olive. I like it and feel it will produce fish for you. Now all you need to do is see if the fish like it, so, go get it wet. It looks good to me....

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
