I think that the crowd should be given a bigger part. Say a hundred are given the ability to judge. As you get more and more people to judge, you'll get a consistent idea of who performed the best/stylish trick just because of the larger pool being gathered from. Thus the person who wins is the one who
A) pulled the best technical trick in the eyes of people who care about that only
B) pulled the sickest looking trick by people who care about that
C) just looked BAMF by people who think thats important
so know you get an overall winner who could pull multiple factors together to win which means he had the best "style"
