Seriously? You're comparing a video of a few seconds from a static angle to following a guy for several minutes over a variety of grades and turns?

I'm not going to critique anyone's downhill technique because frankly, I pretty much suck at it, and I don't particularly want to take the risks I'd need to to improve it at age 58. But you've now upped the ante for being able to critique the video from "you have to be good at downhill", which is reasonable to "you have to have video of your own downhill riding", which is absurd.
