This is a favorite Winter Steelhead Fly of many west coast anglers, not only for it's beauty, but also for it's name. Bill McMillan, a Pacific Northwest steelheader, came up with this fly in the 1970's. It's tied on larger hooks and features very bright colors to move those stubborn winter fish from their cold water holdig spots. It's generally fished on a long leader with floating line. Winter steelhead are said to be the "Fish of a Thousand Casts", but this fly will make them move. It's very nice looking in the vise, but in the water it's amazing. Probably not the first choice in gin-clear water or you'll scare the crap out of every fish for a mile both up and downstream, but in cloudy and murky water, this is the fly to choose. Whenyou tie this fly on a leader, it gives you some added confidence. I know for sure if there is a fish around, it will take notice of this fly.
