Depends if your counting the risk taking element as talent, but I assume when people try big stuff they'll measure the risk and that it's going to be slightly more likely than not that they'll make it. Like for Danny Mac's front flip drop, he'll have tried that on a foam pit or something and knew his success rate was good enough to be able to do it off Edinburgh castle.
But yea, the best riders seem to have a good technique to balls ratio.
