Seems pointless not to ask for the widest channel you can get. Unless you're absolutely sure you're never going to need more bandwidth, then I guess you could be nice and try to leave some more spectrum open, but if there's even a tiny chance you're going to ever need more capacity, I'd just go for the widest you can get.
