If your driving your car 130mph and start getting nervous thats not because you lack the skill to drive your car 130 mph, all you have to do is push the gas pedal. Its because you dont have the balls to go that fast that you get nervous.
And at the game time if your dropping a 130 foot cliff and don't get nervous its just because you have balls, not necessarily because you have alot of skill. Noone is dropping 150 foot cliffs without enourmous testicles.
And with respect to the tech rail stuff. It flatout takes skill and balance to be able to do the stuff most pros, including downey can do on rails. I don't doubt that anyone can do it but you have to develop the skills to do so. And the progression in rails is far more diverse than the progression in cliff dropping. Rails you have so many options of what to do next, whereas with the piere style cliff dropping the only progression is to go bigger.
That said when piere decides to jump a parking garage, i do ejaculate in my pants.
