RE: tough decision
I have had a friend try that shot on a bruiser. Thier is a lot of bone and stuff to go through. If you get to the lungs, You will probably only get one lung. Then you arrow will have a tough time getting a pass through. If you don't get a pass through, there won't be any blood due to the entrance being on top. So your left trailing a buck a couple hundred yards with no blood. Not fun to me.[:-]
