RE: Feathers?
Benefits.
Less weight. More speed. Better FOC. Work very well even if damaged. Can be applied with fletching tape, no need to use glue if you've dipped and or crested your arrows, or even wrapped them. Peel the feather off, rub off the tape, and refletch. They work when wet. They lay flat and look funny, but they work just fine. You will, however, get a puff of water in your face when you shoot them. Superior guidance. More forgiving, especially if they come in contact with something. They lay flat and stand back up, instead of deflecting like a vane does. And, perhaps the best reason of all......They look really, really cool.
