Hey, those are great pointers, I will be gettting a gallon size zip top bag to use!! Thanks for the input!!

Both feather and vanes serve two functions. They correct a bad release and to rotate the arrow in flight. If you bare shaft tune your setup, there will be little negative effect for a mechanical release shooter. On the other hand, a poor release for a fingers shooter will have substantially more negative impact on the shot.

Or you could use a whisker biscuit and not worry about wet feathers!
Seriously. I had some blowhard at an outdoor 3d range one time telling me (after he seen my wb) that a "guy he knew" was hunting with one in the rain and when he took his shot (at a deer) his arrow barely went 10ft.
So being the skeptic that I am , I walked down to the creek , inserted my arrow into creek (fletching end of course) , took some water in my hand and saturated the biscuit , and walked back to where this guy and my buddies were standing at the 20yd stakes. I then proceeded to shoot the soggy arrow (and biscuit) into the 12 ring. The guy then said "his buddy must have been full of s***" and walked away. My buddies said it was the coolest thing they ever seen. When I shot , there was a cloud of mist from the fletchings passing thru the biscuit. Somebody (that shoots a wb) and owns a digital camera should try this and get a pic.

Bowfanatic, I know what you mean about shooting through the WB when it's wet. I've done it hundreds of times and the arrows fly great. That little burst of mist is kind of cool looking.

I don't worry much about feathers in the rain. I'm typically shooting at such close ranges, that it wouldn't matter. For peace of mind, I put on vaned broadhead in my quiver - just in case. I've yet to pull it out to use while hunting.
