Attach a wire or heavy-mono stinger loop to the rear of the shank and lock it with thread and super glue.
Dub a small ball of chartreuse Ice Dub at the rear as a hot-spot butt.
Tie in oval silver tinsel and a long cock hackle by the tip, then dub a UV purple Ice Dub body forward.
Palmer the hackle forward through the body, then counter-wrap the silver tinsel through it to protect the stem.
Build a collar of ostrich herl fibers around the shank, then add a few strands of holographic Flashabou (keep it sparse. Only 3 strands per side swim best).
Tie in a well-marked guinea feather by the tip and wrap it as a soft front hackle for the shoulders.
