These flies are simply beautiful. They also have been Andy's little secret for several years now, his go–to flies for fishing small nymphs, and flies he was reluctant to share or show to others, the cat is out of the bag now however. Perhaps, as Andy surmises, it is the color contrast — the two–tones — that helps pull the fish's attention, with help from the Mirage Tinsel flashback. No matter what, these new flies have not only proven to be deadly little patterns, but frequently have yielded, for some, the largest fish of the season.
