Both are worthy of being selected for a trip; however, as others have said, it depends on the type of trip.

If I could travel with two lenses, either body plus the following two lenses would work for me:
85mm or 90mm f/1.4
If I needed to shoot with long lenses, I would take the Nikon F and the following Nikon lenses from my inventory:
Long telephoto lens (400mm f/5.6)
Medium telephoto lens (80-200mm f/2.8 or 180mm f/2.8)
Wide lens (20-35mm f/2.8 or 35mm f/1.4)
On the other hand, if I were going to be scuba diving or shooting around salt water, I would leave both at home and take my Nikonos III underwater camera instead.
