hey turbo_penguin, what exactly are you implying that an unknown has less to lose? i think what you mean is that theres more to gain, not less to lose.
if a pro hits it and falls, he falls, so what. its the same with an unknown, if they fall, they fall, who really cares.
so lets say a pro lands it switch, he gets alot of props, maybe a few pictures, thats it. but if an unknown were to do it, that would open up all sorts of opportunities for the person, maybe sponserships, exposure in magazines, maybe a clip or two in a movie.
