Hook Heavy-wire O'Shaughnessy such as a Mustad 3407 (a Trey Combs hook also works)
Thread Yellow, colored in at the head with a marker to match the fly
Materials
Fish Hair (tail) Tyer's choice, black and red, yellow and red, chartreuse and orange, or chartreuse and black are the tyer's best combinations (A 12-inch length, doubled over)
Bucktail (body, rear clump) To match the color scheme (One clump)
Bucktail (body, front clump) To match the color scheme (One clump)
Permanent marker To match the fly (To color the thread head)
How to tie it
Lock a large heavy-wire hook in the vise and start the thread.
Even up the tips of a 12-inch length of Fish Hair, double it over at the tie-in point and lash it down so it cannot pull out. The doubled loop makes it essentially unremovable. Trim it back to about even with the hook point.
Take a clump of bucktail straight from the tail with no preparation, tie it in over the rear of the shank with a few wraps, work it around the shank so it is evenly distributed, and give it a firm tug so it flares. You want bulk that pushes water and slows the sink rate.
Whip finish over the first clump before continuing. It makes the fly much more durable down the road.
Tie in a second clump of bucktail in front of the first with exactly the same procedure: three loose wraps, spread the hair around the shank, tug to flare it, then bind the butts down.
Wrap the clipped tips down into a clean tapered head.
Whip finish, then color the thread head with a marker so it matches the fly.
