I don't totally agree, perfectly tuned arrows will fly well with wet feathers or even NO feathers, thats one of the reasons I make a big effort to tuned my setups as good as I can, because there have been times I have hunted in rain for a week straight and there is no way you can keep your fletching dry in those conditions. Make sure your broadheads are on straight, tune them well and don't worry about it. I DO flick the fletching end of a wet arrow before I shoot it to remove the excess amount of water AND because of the reduced feather surface, your arrows will be more susceptible to a sloppy release. A lot of sins are hidden by big dry feathers, but we don't always get to hunt in those conditions.
