I would like to see more high school teams at some of the bigger events...not just USA. I know team cheergyms, West, Clovis high, and Notre Dame make appearances at events other than USA comps, but if more schools went to these events then there would be WAY MORE competition for these few schools and it would be more exciting.
USA events cater to schools more, plus they are cheaper. That is one reason why many schools compete with them. Also USA Nationals is a very large high school nationals on the west coast, so why not attend those comps. All star teams are there to compete so they can go to many different comps. Many of these companies are around based on the all star industry alone.
