Human strength alone cannot smooth out that ride.
I don't see where the specie of the tree factors into anything. The climber took too big of a top for the guy running the ropes to handle.
I blame the climber for trusting his ropeman to handle that load.
Then, I blame the groundy.
I know the climber in the video. He's a good guy. I haven't talked to him yet, but from what I understand he walked away with only minor scratches and bruises.
I have no idea why he tried taking such a big top. Norfolk Island pines are totally unforgiving in this regard. I think he definitely learned a lesson of some sort!
