I was hesitant on shooting arrows with Qwik-Spin vanes as my son was shooting them at his camp . I could tell when he was shooting the Qwik-Spins as I was down range , elevated and off to the side of my son . I fletched a few and they flew great . I could hear them fly through the air from the side but have no idea of what they sound like down range . Minimal string noise .
I used them last season and shot a 6 point buck at 35 yards - double lung shot .
