As far as I'm aware everyone last year was at least working on bronze, but that's not to say you wouldn't get something out of it at level 9. Are you a fairly confident 9? Would you try new things? If so I'd say go for it. It's aimed at any level, it just so happened that no one lower than bronze went last year. They split it into ability levels and there's plenty of help on hand if you're struggling with something. The coaches last year were all really great. Hope this helps you make up your mind.
