So you've cracked two lightweight mavic rims and are thinking about getting a third? That's not what I'd do.
The Deep V's seem to be pretty popular amongst city folk but they seem a little heavy to me. What about the Dyad? there lighter and cheaper and alot of people trust them for touring? Seems like a touring wheel is what you need. They're a bit wider but I think Carp's point about using wider tires might be a good one if potholes are a problem.
