Mitchie Brusco’s only critique seemed pretty spot on, when he pointed out that one of the fun parts of watching Greyson is watching him land and seeing the rollaway.
They cut the roll-aways (and some of the roll-ups) in the video in order to create a sense of speed and energy. Part of the fun of watching Greyson is watching his style, and you don’t get to see that in it’s full effect when they cut everything early.
