Chuck,
I agree with everything you said, almost. Now I do not make films, but I have seen hundreds of them through safety orientations that I have attended, and like I said I work construction and was a fireman for 20 years. I am required to wear a full body harness on these jobs, and I have been there done that also, as far as falling goes. It is no fun in a harness either, no matter what anyone tells you. My statement was to allow just enough slack to sit down, some guys hook these things right behind them, no need to fall 4 or 6 feet if you don't have too, that equals several thousand pounds of pressure on ones body. The part I did not agree with was what you said about these new hunter harness not having a strap issued with them, the ones I have bought sure had one. We wore belts for years on jobs and they saved alot of lives, though the harness is better, for working. But it too has falts if you hang for an extended amount of time. I will keep my belt for hunting though, there is no way I can even step off my stand if I wanted too, not enough slack. If my stand breaks, all I have to do is step on my ladder. Nothing is full proof though. JMHO...I am not an expert either. Good hunting my friend, and I pray neither of us really ever needs these while hunting.
