Feathers all the way. I began shooting vanes and when i began workin up at the bow store, my boss swore by them. Finally, I broke down and fletched some up and i will never go back. Yea, vanes are more "durable", but ive actually refletched less feathers than i would have vanes, and thats with everyday shooting of about 40 or 50 shots. They are more stable, even in the rain. Now my boss is tryin to get me to shoot Zwickeys. Maybe next year.
