My friend and I were just discussing this broadhead while watching Hank Parker's Flesh and Blood show last night. We both agreed on basically the same thing. Without a pass through you're in for a hard tracking job. What if you hit the opposite shoulder? I'm sure the deer will expire and will have a lot of internal damage but you would likely have a hard time finding it.
As for a quartering shot - I've never had any problems with any broadheads. Of course I never shot at a deer that was hiding behind a sheet of plywood!!
