The original called for a woodcock hackle, but since I don't have any woodcock I used a sharptail grouse rump feather which I think might be a pretty good substitute. You guys that tie with woodcock might be able to chime in on that.
The original pattern:
Body: ash colored silk thread
Rib: open wraps of natural heron herl
Hackle: woodcock

Then, along the same lines, here is a couple more I wound up.
These are tied using Pearsall's silk thread in gold (waxed) and the sharptail grouse rump feathers again.
For this one I used natural rhea herl for the ribbing

...and for this one I used a cock pheasant center tail fiber dyed ginger for the ribbing

and a folded split wing just to be a little rebellious
