A very simple fly of Z-lon tail, maroonish-brown thread body, brown rabbit thorax, grizzly hackle, red thread (6/0) head on a size 12 hook. Nothing fancy needed. Simple, effective patterns often beg for amendments: ribbings, wings, flash. I am prone to this, as it is part of the fun of fly tying and fishing. Simple wets, large to small are effective, with presentation/location as important as adding flash and dash.
