If you want to contact Davy directly, he posts frequently over on the flyfishingarkansas.com board. I do believe that the 3 fly method he illustrates in the video you speak of would preclude the use of a winking fly line. I have the video, a copy that Davy signed for me in his living room one afternoon last summer. I just can't imagine myself trying to keep 3 flies from tangling. I have enough trouble with one of them.
