Rooster hackle, palmered as a rib Brown hackle (1 feather)
Peacock herl Natural peacock herl (3-4 strands)
How to tie it
Slide a 2.4 mm tungsten bead onto a size 12 2X-long nymph hook, then put on about ten wraps of 0.015 in lead-free wire and jam them up into the back of the bead to lock it.
Start black thread behind the wire, wrap over it a few times to secure, then run the thread back to the bend.
Snip four brown goose biots. Take two, flip one so they sit back to back and splay apart, and tie them in at the bend as a long tail using a pinch wrap. Cheat them toward your side so that if they spin they end up on top. Add securing wraps and check the position.
Bind the biot butts forward with loose wraps to just behind the weight, then smooth the underbody with a few extra wraps.
Tie in a brown rooster hackle at the bend with the tip pointing back, leaving a short length of bare stem exposed so the first turn lays no fibers. Trim the excess.
Tie in three or four strands of peacock herl at the bend and park the thread just behind the bead. Wet your fingers, twist the herl into a loose rope, not too tight or it breaks, and wrap it forward to the bead. Tie off, break or snip the excess, and add securing wraps.
Palmer the hackle forward in fairly close turns to the bead, tie it off, and trim.
Trim the hackle flush across the top and hard down both sides so the only fibers left are the ones hanging below as legs.
Take the remaining two biots, leave both concave side down, line them up in a shallow V over the back, and set them with two loose wraps. Adjust, then add about four careful tight wraps. If they roll, back the wraps off and try again.
Push the biot butts up, bury them with thread, and build a smooth base between the bead and the wing. Whip finish and put a drop of head cement on top of the bead so it wicks down into the wraps.
