In just a few hours (early Sunday morning) I'm heading down to Moab, Utah to hit Arches NP and possible wonder in to Canyonlands NP. I have the D2Xs, 12-24mm, 28-70, and the 70-200mm packed. But I'm really eyeing swapping the D2Xs out and taking the D200 instead. No real reason for thinking of swapping other then saving a few oz. Hell I'm sure in the end I will just end up hiking with both of them. For those of you that have been to Arches before, do you think I will use the 70-200mm that much?
