I also dub the head with marabou fibres. This gives the fly a nice silhouette. On this version I have used a nickel cone head. Black fox 2.5 to 3 times the tube lenght. A couple of strands of flash.
Whip finish at least two times.
I don't varnish this fly because it will ruin the marabou dubbing, but I use a drop of superglue to fix the thread. Global Fly Fisher . All rights reserved.
