Pros for me would be the gapping exit hole and the blood trail if needed. I also don't worry about accidently hitting the broadhead razors on my bow string.

Cons for me is that the blades aren't very durable and even if you wanted to change them it is more time then it is worth. But Iknow guys that get a new bow every year or every other so what is a few bucks for a new pack.

All in all I like them and use them on whitetail and bear.
