Is it better to select only one office or more than one?

I know one can select more than one office during the application procedure at MBB. From my perspective, I would rather indicate more than one office to diversify a little the risk. However, I don't know how this is perceived by recruiters. If you choose more then one, do they appreciate it because you show you are willing to travel, or, on the contrary, do they perceive it as a sign that you are not committed to your first choice?
