any kind of competition is possible with the right kind of audience and good level of contestants

I know we could hold an all lower competition no doubt,
sure, crowds can't relate to how difficult it is, but eatw combos still look crazy as fuck. You don't need to be able to relate to something to understand that is looks fucking awesome. Motocross is the same concept, we will never understand how difficult it is, but it still looks sick.
There's another that visits me on occasions, and people would rather watch his nt combos than anything else, it's appealing to the eyes.
Lower freestyle isn't as boring as we make it seem, if you can remember the first time you saw a rocco video that's the same experience a crowd would get. Mind = Blown.
