The Thor is not only "like the old, standard flies", it's one of them. It was first tied by C. Jim Pray and was named for Walter J. Thoreson who used it on the Eel river in 1936. Most of the traditional white-winged steelhead flies were tied with polar bear hair and a Skykomish Sunrise, Polar Shrimp or a Brad's Brat tied with anything else is only a pale imitation of the original.
