I remember tying them back then worked really well. I'll have to tie them again..been using clousers for years now. hen mallard works just as good as the pheasant feathers too. hm dying them bright colors for steel, now that's an idea..
Dying is a good thing as the crayfish that live in the brooks near your home and those that live in the Loyalsock for instance have slightly different color in the carapace. When I traveled around the Northeast I found many different color phases of the crayfish and so began the dying of the hair in order to make a better facsimile.
These things worked well fishing small mouth bass in the West Branch of the Susquehanna also. Matter of fact I caught more bass than trout using the pattern.
