An axe to grind? Fucking please. I suggest you go back and re-read the first few comments
here. You could have simply accepted the constructive criticism that others had to offer, and made it a learning moment. Instead you chose to get defensive, begin insulting men who have been in the saddle longer than you have been alive, call folks soft, and continue with your storyline that there was no operator error while you and the peanut gallery were pulling over that spar. The problem is that your vid tells a very different story. The story of a self taught tree-man who clearly doesn't understand that allowing a spar to sit back on your wedges is never a good thing , and continuing to do so will eventually lead to disastrous results.
I hate to admit it, but I agree with Rico here. Yes, he is harsh and rude and ugly and has little care for the truth, but that's just him. Best not to take it personally (good luck with that) and re-evaluate.
I think that leaving a spectator in the DZ is a whole lot worse than the little bit of rock back, especially on hemlock with no side lean. But I think we can all agree that together, they compound the danger. So leaving ANYONE in the potential DZ is a systemic problem that needs to be corrected.
One of the best climbers I ever worked with got all upset when I shut him down for running the blower before falling a tree that had obvious lean away from the lawn where he was working. He had just topped the tree and there was zero question that he was in no danger. BUT that is a safety policy that I don't violate. No one in the potential dz (say 110-115% tree height) before the back cut starts, except the faller. There were a couple of new guys there that day and I didn't want to set a bad example, so they might get the wrong impression that it's ok to be in the dz. For the little time and energy it takes to clear the dz for the short time it takes to fall the tree, that policy makes sense to me.
Brady's video is also a good example of a situation where improving technique will lead to obvious safety improvements. If you had doubled that line on the top of the spar, natural crotch, tied one end of to a ground anchor and set up the same 3:1 z rig on the other end, there would have been near twice as much force on the tree, so you wouldn't have to jerk the line to get the tree moving. You could have had a nice steady pull. You might not have even needed the third man. That would have been an easy and effective solution, making the job both safer and easier.
And if you needed even more pull, it's not hard to set up a block on the working end of the pull line for 2:1 system, and then use your 3:1 on that.
