Start the pale yellow thread and lay a smooth base to the bend.
At about the 65% point, stand a small bunch of natural/dun deer hair upright and fan it 180 degrees across the top as a Comparadun wing (no hackle).
Tie in a short tuft of gray (or mayfly-brown) crinkled Zelon at the bend as a trailing shuck about a shank length long, and carry a few strands up the underside of the wing for extra flotation.
Build a slim abdomen with the yellow thread (or dub sparsely with PMD Superfine) from the shuck forward to the wing.
Dub a sparse PMD Superfine thorax around the wing base to lock it upright.
