Upvote just for the first time I've ever seen slow motion done well on YouTube.

I'm trying to imagine how painful it would be to fail the trick.

My local rock gym had one of these up for a few months. When someone slips, the sound of the webbing just smacking them in the groin- it was great fun for everyone. Then some 250-pound football lineman tried it and actually managed to blow the bolt out of the wall. Fun while it lasted.

I wonder how many times this guy had to practice this before he could do it without racking himself.

karaid, most people don't use a good digi cam that has a 60fps video mode.

Silly little cell phones don't cut it.

man, i was thinking the same thing. "that's a pretty good frame rate for a vid cam."

It's harder because it's a blind landing.
