On the rear hook, tie in a clump of tan marabou on the bottom and a clump of white marabou on top (the fly rides inverted) so the tail runs a bit longer than the shank; clean the fibers with a thumbnail before tying to keep the body slim.
Build a dubbing loop of gold metallic ice dub, spin it tight, and wrap it forward to form the slim rear body; whip finish and trim.
Brush the ice dub and marabou rearward with a velcro tool so they blend into one flowing profile.
Start thread on the front B10S hook and lash the rear hook to it with articulation wire, securing the wire down both sides of the shank.
Tie the tungsten streamer eyes on top near the hook eye with figure-eight wraps and wraps around the base, then lock with superglue.
Add a gold ice-dub dubbing-loop collar behind the eyes, then stack and spin deer hair over the front to build a bulky head.
Whip finish and trim the deer hair to a rounded, water-pushing head shape.
