The Gnarlyness of this is not the trick, its how it looks. Im sure this dude could do the gap switch. But that Heelflip is fucking gigantic. Who gives a shit if Shane Oneill 540 flipped it. Or if Cody Cepeda nollie 360 sex changed it. Dont care.
It's sort of what I like about Alex Olson. He usually doesnt do the most "progressive" trick, but he does whatever trick he is doing better than others. Tiago's heelflip is proper, beautiful and high as fuck. Nothing more needs to be said.
