Slide the copper tungsten bead onto the barbless jig hook, small hole first, and seat it against the eye; start the thread behind it.
Tie in 4-6 pheasant-tail fiber tips at the bend for a short tail, half a shank length, and tie in the copper wire alongside.
Wrap a bundle of pheasant-tail fibers forward to form a smooth abdomen up to the 70% point, then rib with the copper wire in 4-5 evenly spaced turns and tie off.
Dub a small peacock UV Ice Dub thorax just behind the bead.
Wind a bright fluorescent-orange (or hot-pink) collar in the gap right behind the bead, this is the hot cheek/collar hot spot, then whip finish tight against the bead.
