I am new to fly fishing and tying. I live in Colorado and primarily fish for trout. I go to the fly shop and there are so many choices in materials that it is a little overwhelming. I have only tied the basics so far with little variation in color or material. Wooly Buggers, Elk Hair Caddis, Adams, Pheasant Tail, Gold Ribbed Hare's Ear, Ant. Any suggestions on other materials and colors for thread, chenille, hackle, dubbing, marabou, etc., that would be useful? I mostly have black, grey, and olive material.
