Byron asked me for my version of this fly, which is a little different. (At that time I was out of CdC but as some arrived yesterday...) I tie a gold ribbed hare's ear version.

The body is tied in two sections, the rear two thirds is dubbed hare's ear ribbed with fine gold oval. Then the forward third the same hare's ear in split thread to give a hackle like thorax. Working in from the eye I clip a V in the thorax hairs. As always with Hare's ear flies a primrose coloured thread shows off the hare's ear best, in this case 8/0 Light Cahill Uni. This one is on a size 10, usually I would have them in sizes 10 to 14.

The antennae are omitted as I find they don't add anything to the fly. Often the first fish will break them off anyway. I have never perceived any difference in fishing these with or without them.
Cheers,
