The BuM Luxos U has been plagued with failures. It is an awesome light, but I wouldn't take it into the woods. For one thing, it's huge and heavy.
I didn't really follow the tour divide. The three people I know that have ridden it used dynos without issue.
I'd argue that in the spirit of other technical trials, unideal environments provide good data on products we might be considering.
But I also figure that isolated incidents will get more attention on something like the Tour Divide, so a product that is otherwise very reliable might get bad press for nothing more than some bad luck.
