I have had great luck with my heads and they are chisel point, they have been great on all north american game. A long time ago I considered the COC heads when I first started hunting with a bow but after making a bow hunt for a week in south texas and taking three large pigs with pretty thick sheilds, I came to the undisputed decision I was sticking with my heads. That has been 10 years ago and they have never failed to do their job. I am not one to change just b/c something new is out, so I have never thought about it again. I would consider a COC b/h if I were to go hunting in Africa and hunting a really tough skinned animal. Other than that sticking with what I know and trust....
