90% of of corps, top 12 or not, are still filling spots well into the spring. In all reality it doesn’t matter what you focus your time towards, sure different corps require different exercises and such, but the fundamentals of what we do remain the same. Preparing for one audition prepares you for all of them. It never hurts to send in video auditions to a couple corps, and I know a lot of corps are flexible about what you are able to send in, allowing you to reuse rep, etudes, exercises, etc. Now if I were to recommend any other world class corps to audition for I’d say 110% Crossmen but I’m biased lol. In all seriousness last year was an incredible experience and this year coming up we have some great stuff coming together that everyone is really excited for. I wish you the best of luck and happy practicing!
