Best cost/benefit of many materials for tying, given the price of feather materials today. Will tie many flies with this. And likely share it with other tiers in our club.
Although the tippet feathers were full and well-barred, they were also a bit flexible, and thin. But the crest feathers were lush and full, with good quills, and excellent for tying full-dress Salmon flies with little fussing.
