[ Performing Arts ] Open Question : Can anyone give me any advice for the Falcone Euphonium competition?

I've been playing my euphonium for about 15 years. In high school I was in all-county band 5 times, All- Long Island band twice, principal chair, and I made All-State (NY) senior year of high school. Right now I'm just finishing up college and I wanted to conquer the next challenge. The 2010 Leonard Falcone Tuba/Euphonium competition and prove that i'm the best in the nation. Any music people have any advice?? It'd be greatly appreciated. Thanks!
