natural ability has alot to do with any sport. its just like when yall played football there were people who were fast runners and slow runners. not everybody is going to be able to run fast alot of that is natural. in freestyle i think that in many cases natural ability won't hold you back much, but it could lead to the type of freestyler you may become. for example dan magness doesn't look to be the quickest or most limber person in the world, but since he was serious about freestyle and practiced he became one of the world's best uppers freestylers. i'm sure there are many guys on here who could slaughter dan at lowers, but they are not overall as good of freestylers. than people like fx, palle, and others are naturally more limber and quick than others, so they picked up lowers tricks faster than other people. also the extremely hardcore tricks probably aren't possible for everybody to learn.
