I don't know how much my opinion really matters since I may or may not be able to make it to Moab this year, but I wouldn't go for Gold Bar Rim if there are any stock VXers; I went on that one last year and had a small panic attack when I got to the waterfall obstacle. Ended up parking my girl on the side of the trail, and rode with Dave for the rest of the way. Not a real friendly trail for the novice (or for those prone to anxiety and without any meds on board, lol). Fins and Things went just fine though, and I have no opinion on the others, as I haven't been on them...yet.
...personally, I would take on Gold Bar Rim again though. Need to win my woman card back from the trail that robbed me of it
