I've been experimenting with a couple of midge patterns that I've always tied with gold beads and have actually seen an increase in bites and catches. One being the obvious zebra midge with either a copper rib or a gold rib, no difference in bites that I've noticed between the color of ribbing. The other is a variation/combination between a zebra midge and a scud, without the scud back, if you know what I'm talking about. I call it a wooly midge. I usually tie more earth tone colors, tan,brown,black,olive,and grey. So far the only color that I have yet to catch a fish on is the grey.
I haven't had the opportunity to try these on wild trout or Taney yet, but they are killers at Roaring River and my local White Ribbon streams.
BTW, I am in no way a great fly tier yet. LOL
