Yeah. I keep having thoughts about what happens when there are enough airbenders that you could have pro-bending with airbenders. Or what happens when... Milo? Ikka? Jinora? who would be most likely? ...decide to take after Korra and really really really want to pro-bend.

Because I keep thinking that what happens then with the sport isn't going to be straightforward. Because by then, there's going to be the weight of tradition, both with respect to the airbending temple and from the sport's managers/promoters and fans. Multiple traditions, in multiple directions.
