Rowhard,
There are plenty of rooms in Moab so don't worry about roughing it. Also, there are plenty of trails out there with different ratings so you won't bang up the VX. In my opinion, and chime in if I'm wrong, but I would say any trail with a 3.5 rating will be challenging and fun with the potential of no damage to the stock VX. It all depends on the line you choose. No one goes out there to to do any damage to their beloved VX.

I can't think of anyone doing any damage to their VX if they followed that rule last year.

Peace.
Tom

P.S.
I'll be there again this year.
