For what it' s worth.....I used vanes first for a few years and then was put on to feather by a friend. I used feathers for a few years and now I' m back to vanes. I had some minot porblems with feathers....after a few hundred shots they wouldn' t " zip" back together and thus they were taller than originally. That created some clearance problems after a while. I also have problems with vanes....one touch with a field point to the vane and that vane will tear and never fly the same. Either way both need to be replaced when worn. Vanes have worked better in the rain than fethater for me, but Davidmil hit it when he said that the effects of rain are minimal if your setup is properly tuned.
