For hunting distances yes. But for target archery, no. The same drag that makes them more forgiving of shooter error (they will not make up for bad form) causes them to slow down faster than vanes do beyond 40 yards.

I tried feathers several years ago and I just couldn't get the darn things weather proof. I sprayed them, dipped them, rubbed powder in them, and the first drizzle that came along flattened them out every time. Vanes are fool proof. Even if you punch a hole in one practising, just clip it out and keep on keepin' on.
