When I lived in High Point, NC...we used to have tryouts on different dates. But kids would try out for two different clubs...and then decide which team they would quit...this would mess up the roster count of one of the clubs...It would also leave an empty space which could have been filled by a kid who had the desire to be on the team. Eventually High Point figured this out and made us make a decision which team we wanted to be on. I think it should be like this.
