I glanced at the itinerary, I think I've ridden everything on there (a couple descriptions seemed a bit vague) While I love my hardtail and think most of these trails ride pretty good on a hardtail, the stuff over on brian head peak, particularly if you're headed down dark hollow/paradise canyon you'll likely prefer the FS. Parts of the VRRT has some rubbly rock that might get a bit old on a hardtail too, depending on how many miles you're riding.
