Al Caucci and Bob Nastasi's Comparadun concept changed dry-fly design. The fanned deer hair wing sits flush in the film like a natural, and the split tail provides perfect balance without hackle.
1. Thread base — Attach yellow thread behind the eye and build a base to the bend.
2. Tail — Spin a small clump of dun hackle fibers or antron onto the thread, divide them into a V-shape, and secure at the bend to form a split tail.
3. Body — Dub a slim, smooth sulfur yellow body from the bend to the 2/3 point.
4. Wing — Stack and align a substantial bunch of deer hair. Tie in at the 2/3 point on top of the hook with several tight wraps. The tips should flare forward over the eye — pull them back and post with a few wraps in front to fan the wing 180 degrees. The wing should sit upright and fanned like an open fan, one hook-gap in height.
5. Thorax — Dub a small amount of sulfur yellow dubbing around the base of the wing on both sides to finish the thorax.
6. Head — Whip finish behind the eye and apply head cement.
