Well...I guess I agree since I have 4 or 5 different versions of a beadhead pheasant tail. Some with brass...some with black nickel, some with hot orange or pink...and then of course the pt nymph without the bead.
Can't say it is a conscious thing for a particular river or stream. Sometimes I happen in to the right one through trial and error. And some days flash works...some days it doesn't....and some days you throw an egg pattern and vladi worm on the end of your tippet and pretend your fly fishing...![]()
