I use lemon wood duck flank feathers quite a bit on duck jigs and fish love them. I trade jigs with a guy for wood duck feathers and have a good supply,even dyed some pink. They aren't just for dry flies.I prefer the one's without the white/black tip. I put the one's with the black/white to the side and use the other ones. Whether the are mallard,gadwalls,teal or wood ducks they all work great. I don't know why because they don't have action like other baits but they have caught thousands of fish for me in the years I've been tying them. It's probably the barred coloration they have,look more like a minnow then anything I've ever used.
