Like in this example, [url=http://www.flyanglersonline.com/features/oldflies/part398.html:b8dbe]Bergman's Chateaugay[/url:b8dbe]. The only info I could find on the net was using "rolled" wood duck flank, [url=http://globalflyfisher.com/staff/petti/garage/woodduck/wetflies.htm:b8dbe]here[/url:b8dbe]. That doesn't seem tp be the effect that Eric gets for the wing. It seems more upright. Is this the same as tying matched wing slips from duck wing feathers? Or am I out to lunch here?
