I'd say ask yourself this-- if you were going camping with buddies or to a festival... would you rather have your Davis with you, or would you be worried about it being vulnerable and wish you had something you cared about less? If the answer is the Davis... get a great case so you can bring it everywhere with you. If the answer is you'd be worried... get a second mando that you like well enough to enjoy playing in those places where you'd rather not bring your cherished monster.
Either way, you're buying protection for the Davis. Either by putting a good case on it, or by providing a "stunt double".
