I am a feathers guy. Here are my thoughts. Trust me, vanes work. Just some thoughts if you ever wonder why some of us continue using feathers. (or secretly want to try this but you always get wrinkled noses, at the archery shop, when you ask). Here in Texas, at Archery Country, they have just gotten used to me.....or maybe disregard? Oh boy!
I gather from the title you're a drunk gay rancher with an odd fetish for veins and birds? Weird but whatevs. Enjoy!
