Hell, I'm a minimalist. My favorite fly is what I call the guide's version of a gp. Quickly tied without hackle or eyes, 3 segments in a couple of different colors, black, red, orange, purple and most on one size hook (1.5) with the dressing made smaller or larger for different conditions. Simple. As far as winter fish are concerned this is about all I think you need. A once famous guide (I guess he is still famous) threw a fly down on the counter at the old Skagit Anglers fly shop that looked an awful lot like the one WW posted a pic of and told me this is all you need for winter fish. I believed him.
