My "control" group is the deer I killed this year. I've tested my BH choice through enough DEER, now, to allow me to say I'm completely satisfied with my choice.
I didn't even look at the video....but I will as soon as the deer start wearing wood and metal armour. Otherwise....I think's it's a moot point (or an attempt at one).
I think David's correct, too. I bought 6 a/c/c's to start my deer season off. There was one that WOULD NOT fly straight.....no matter what I did with it. Imagine if I'd shot that one, first......and made my decision on a/c/c's from that one arrows flight characteristics.
