I use 4inch right helical feathers with mine they work great. dont wear out like the vanes when shot alot, but the edges will tatter a bit. as for hunting in the rain I only take two arrows with me deer hunting anyway if it rains and they need to be replaced early so be it. Also you could buy a jig and refletch/put togetheryour own arrows this is very easy to do and will save $$$ if you shoot allot or are rough on equipment.-just a thought
