Thanks guys, this gets me out of lurker mode every now and then.
Trapper Rob, good question, but I don't have a definitive answer for you. I've made a number of these, and they were very commonly done like this back in the day. With my personal experience, I haven't noticed a huge difference in mixing the feathers. Regardless of how I mix or match wings and/ or tails I have some that fly really well, and some that fishtail. I just make sure the top sides and bottom sides of each feather are facing the same direction. I don't use a fletchings jig, a spine tester or anything to determine weight, so I think these factors probably have more affect in the flight of mine. Back when I made a lot of arrows, I would just separate the good shooters from the poor ones.
I have often heard the argument that accuracy was not as critical for Plains Indians using shorter bows and riding right up beside their quarry. At one time I espoused the same notion, but I disagree with that idea today. Accuracy is important at a distance, and up close! Curtis
