Hey Folks, The bag that came with my Christopher is just a nylon shell with no padding at all. I am looking to upgrade to something that will provide better protection, and I am considering all the usual suspects like Morradian, Bobelock and Kaces. The new Upton bag with wheels looks especially interesting since it has both shoulder straps and wheels. Also, I don't know how much bridge protection any bag can provide but I would be interested in your experiences regarding protection and wear. Your input is much appreciated. Thanks . . .
