If you have the time you really should check out all the Halls. If you are just into TMCC, Legacy, & DCS, and other modern stuff than the Orange Hall should be your first stop. There is plenty of modern in all the Halls but probably Standard, Post War, MPC, & Flyer make up the bulk of the member Halls. I don't think you get the full York experience if you don't see the other halls.
