That head has been beat up pretty good on the forums already. Just looking at it makes me think it's a bad design that virutally guarantees bad penetration. Take that silly ring off, and it might make a decent broadhead.
I think the ring would kill penetration. If you want to bore a hole in something look at the dead head 6 blade. If that dosn't give you a big enough hole nothing will!
I have not first hand knowledge, but I don't like the looks of it! If I am not mistaken antler eater tried one last year, he got the deer but penetration was pretty poor.
