Yes, failure to deploy is a real concern of mine as is the hard quartering away shot angles and sharp downward angles while in a treestand, but that is why I am trying them now that I couldn't shoot that 200" monster anyway
God, can you imagine? I would probably fall on my own arrow if one came by and I couldn't shoot it.
I am planning on using them on elk next fall in Montana, but I have to shoot a deer to make sure I get a pass through with enough left to feel comfortable shooting them on something as big as an elk. Mainly, I want the better blood trails. With the heads I am using, an elk's muscle is so thick, and the hole not quite big enough, that the muscle covers over the hole and none of the blood comes out. We have actually lost 2 elk including a nice 5X5 due to the lack of a blood trail. If these heads can help with that, then they are well worth the $.
John, anything worth doing is worth overdoing IMO
