Slotted tungsten bead Black or copper slotted tungsten bead (1)
Straight pin / balance pin n/a (1)

Flashabou Pearl / Purple flashabou (2 strands per side)
Simi Seal / dubbing (body) Black or olive chenille ice dub (pinch)
How to tie it
Mount the jig hook and lay a thread base along the shank.
Bind a straight pin (with the bead pushed onto its point) along the top of the shank so the bead sits just ahead of the eye; this balances the fly to hang horizontally. Trim excess pin and lock it down.
Wrap the thread back to the bend.
Tie in a black marabou tail one shank length long, and flank it with two strands of flashabou down each side.
Dub a shaggy Simi Seal body from the bend forward to the bead.
Pick out the dubbing for a buggy leech profile, whip finish behind the bead, and cement.
