Sometimes I' m forced into shooting vanes when vane fletched arrows is all that' s available in the size I need and I' ll shoot them until the vanes are screwed up. Shooting nice, tidy groups or getting stuck in a group of nock-aimers at a 3D, it doesn' t take long at all to get a dozen vane fletched arrows to needing a re-fletching. I always go back with feathers.
Quit putting yer darn arrows where I want to shoot!
I use feathers for hunting. As already stated, there are several products available to help protect feathers from getting wet.
And if it is raining hard enough to still get them wet, it is raining too hard to shoot past 15-20 yards anyhow.
