six to one, half dozen to the other.

Do you have Traction Control (ASR)? If you do, then either rear end is an option, if you do not have ASR, then you will lose ABS with a 9".

With limited track exposure, both rear ends will hold up fine.

With your 18-hour long trips you have a little bit of deciding to do there. Moser 12-bolts are notorious for howling like crazy when Moser sets up the gears. If you get a 12-bolt, be prepared to have to spend more money after the fact to get the rear gears re-setup by a professional. The 9" doesn't seem to have the same horrible howling problems the 12-bolt does normally... but the 9" will possibly make more noise than a 12-bolt even with the gears resetup (due to different positions of the pinion gear).

I personally have a Moser 9" and love it. I put a good 20-25k miles per year on my car.
