Moot point, really. Open and Advanced will compete together for the first prize trophy, so it doesn't matter which division you sign up for. The difference will be in the PDGA points. Competing in Advanced earns you points towards qualifying for Am Worlds in 2011, while playing in Open gets you points for Pro Worlds 2011. Which one do you want to try to qualify for?
