Surprisingly, I actually had several, but mostly when I was young stud and rock solid and when I shot FINGERS. Now what's up with that. Since I switched to a release and carbons.... nadda. Might be too because I now install ACC nock insertson all my arrows. If creates a little flange that makes a lot of arrows slide off after tearing up the nock and adapter. Besides that, I try to spread my arrows out now at different spots. When I shot 2314s Super Slams you could tear up a lot of arrows if you tried. It's too expensive now to be busting up $15 arrows.
