I would think seriously about the Crossmax XLs. I had a customer bring his bike in that had those. He had broken a spoke, which is definately bound to happen eventually. He does race this bike, so he has crashed a few times, not to mention gotten some pedals jammed into his spokes. That was the first time anything snapped.
What impressed me was how straight that wheel was with a missing spoke, even after he rode back to the trailhead. Due to the way the spokes go in those things, he was never in danger of the spoke flying out sideways and getting jammed in the frame or derailleur. He simply stopped, removed the spoke, and kept riding. Then, when he brought the bike to me, all I had to do was pop a new spoke in and tension it. Didn't have to remove the tire, cassette, or brake rotor. I had the new spoke in and the wheel trued up in just a couple of minutes.
Another cool thing about Mavic is you can pay an extra 10% and get a lifetime warranty. It is called the MP3 plan or something like that.
