Two very nice ties! While I've always been partial to Steelhead hair-winged flies, I personally liked the look and lines of your Spey version. I'd wager it'd do quite well in Scotland as well as the Northwest.
It was also nice to learn that the original fly was tied with the materials you happened to have 'laying around' at the time - sounds very much like the frugal angling pioneers of yore.
What type, brand-name, (synthetic, natural, or otherwise) and specific color of dubbing did you use? It appears to be a nice golden yellow or pumpkin and a nice contrast the red'ish tones in the fly's body.
