Yeah as a matter of fact. I have a lot of first hand experience with them. I owned a biscuit right when they came out and took it off a week later. I hated it. I worked at Gander Mt. for a year as well and saw more problems from people using them than I care to share. I've had a lot of friends use them as well and toss them because of fletching damage. Working at Gander and at a local pro shop I've seen almost nothing but problems. Sorry, but that's the experience I've had with 'em and it's been a lot of experience.
