Use trukey feathers and you wont have the problem. If you use chicken feathers, just spray them with silicone spray. Problem solved. When I use chicken feathers, I spray them with silicon because dew can colapse them as well a rain.
Exactly some people dont know what type of feathers are being put on there arrows. And also high poundage bows shouldnt use feathers anyway, the fletchings collapse on release and there is no stabilization. for a good 10 yards. Trust me try to find some high speed footage of feathers. they collapse and you get sort of an archers paradox in a way.
