Wapsi Dry Fly Rooster Necks: # 1 Grade. These little birds are from India and are closely related to their native wild fowl. Originally, they were the only good source of stiff dry fly hackle. Very dry with good feather count, ranges in size 10-20's, lots of 12 - 14's. Not as long as modern hackle but very usable with plenty of tailing material.
