Yes, it's a "good" video... mostly pro's, rather than the typical "mom wanted to try the YZ" stuff that so many of these seem to focus on. That being said, watching these is kind of like looking at a car wreck. You don't want to, but you have to.
The worst one; the one I don't need to see again, was Roczen's launch that destroyed his arm. I'm still shocked that he was able to came back from that and has actually been a front-runner. I def lack the drive these guys have, I can't comprehend how someone could be competitive after that. Dude was lucky not to lose that arm. Still, I think that was the end of his best days, he hasn't been the same since.
