I used to shoot only feathers because I could loose some piece and were still quiet and flew great. I have had vanes for last 1.5 seasons and seem to have more wobbly flight with my FP, but not on every arrow. I am currently looking at the Gateway Razr 2" feather vs 2" blazer or duravane.
Even wet, mine always flew true.
