Well All 3 are very important, but to have a braodhead fall to pieces upon impact no matter where you hit it is worse I would think... There are arguments to both sides, and either one could leave a wounded animal in the woods, which we all don' t want to happen... But I have learned that 2 holes is better then 1, especially shooting out of a treestand where your entry hole is going to be high... Without a second hole to bleed from the animal will just bleed internaly and you may be hard pressed to get a blood trail, and then you are in the same situation... But Needless to say you should shoot a broadhead that works for you, and provides the best of all 3 for your setup...
