This pattern was featured as a Fly of the Month over on Fly Anglers Online. Pretty simple tie, with several unique steps. The over body is Furry Foam. I substituted 2 layers of 2 mm tan closed cell foam for the under layer/gurgler portion of the fly. Was much easier than using 3 mm foam and cutting it with a razor blade as shown in the article. I also used Pearlescent Estaz for the body, rather than the chennile in the article, as I couldn't find the stuff the author tied this pattern with. These are destined for Kamchatka in July for a fellow out of Georgia. He was looking for a waking pattern, and these appeared to fit the bill.
Here's a link to the article:
