That's funny, I've shot a couple of my PSE Carbon Force Extreme 400s into my wooden fence and pulled them out w/o any noticable damage. I've spin tested 'em and continue to shoot 'em. I shot them into the fence behind my deer target while teaching myself to shoot to my extreme right (I'm a right-handed shooter) from a sitting position in a tree stand. That's not any easy shot!

I did get some Vapor Pro 4000s and will test them out.
