I’ve used those and the quick fletch too. They come off pretty quick when you blow through an older target. Other than that I thought they were pretty good. I actually saved a couple that came off thinking I’d reuse them at some point but never got around to it.Anyone remember NAP Quick Spins? They claimed to spin the arrow quite a bit faster than other designs, with the little kicker on them. Probably not for the Whisker biscuit. I used them when they first came out, with a drop away rest. When I ran through those arrows, I ended up with Blazers. I really was shooting good when I had those Quick Spins, but don't know if the fletches had anything to do with it.
