How to tie it
Start the Sumo 50 denier thread and add tungsten at the thorax. Vasies is explicit that you should use tungsten rather than lead here, lead wire bulks the body out and this fly depends on staying slim.
Tie in a bunch of pheasant tail barbs at the bend pointing rearward; these will later be pulled forward as the back, so leave them long.
Wrap the A8 Perdigon flat body thread forward to the 60% mark to form a smooth two-tone abdomen, then pull the pheasant barbs over the top and tie them down. The contrast between the flat thread underneath and the pheasant back is what makes this a bi-colour fly.
Dub a squirrel mask thorax over the tungsten, keeping it compact, and tie in partridge barbs each side as legs.
Pull the remaining pheasant barbs forward over the thorax as a wingcase, tie off and trim.
Wax the thread before forming the head, Vasies insists on this, because wax makes the thread grip and stops the head unravelling after a season of fish. Whip finish and cement.
Tie it small for best results; at size 18-20 it takes trout, grayling and even whitefish.
