When I posted my comments regarding the original post, I was simply making a statement about quartering away shots and not referring to his comment of a "straight away" shot. My purpose was to inform hunters of the quartering away shot. Now if you look at his picture, it definitely was a quartering away shot and not a straight away shot.
As mentioned before, in a tree stand the angle of attack is NOT parallel to the buck's body, thus extreme caution and one's best judgment must be made. I think that all depends on the individual's ability as an archer and a hunter. I for one am not an expert archer but I do know my limitations. I haven't crippled a deer in decades because I do not take shots I'm not capable of executing perfectly. I am by far at the bottom of the totem pole as an archer, with regards to being a career hunter. I don't have a problem knowing that my shots stink at long range, so I simply don't take them! Because I am aware of that, deer don't get crippled and my shots pay off. On the ground, you simply cannot find a better, more lethal shot that also hides your draw movement. I think when charlie 01 asked the question, you should answer that based on YOUR personal ability and not his. If he can take that shot and do it consistently, more power to him.
