Until they've been through a few targets and start to tear off. Then they're LOUD. But still fun.FWIW - a friend and I compared AAE elite plastifletch 3" vanes with 3" predator vanes and blazer vanes (all else being exactly equal) head-to-head, and found the AAE's retained the most speed (and KE) at 40 yards, and were the quietest by a good margin.
