I have an LT and a Superlight. For me the LT feels like a little overkill for most of the trails nearby. As for vacations, it was great when I lived in Tahoe and treated me quite well on trips to California, Utah, Idaho and Oregon. These days though, I usually only ride the LT at the Shed, Gambrill or Elizabeth Furnace. That being said, as a "one bike quiver" you can't go wrong with it. If I didn't have the SL for Wakefield, Fountainhead etc, I'd have no problem riding the LT every day knowing how fun it is to be on. In fact the only reason I don't ride it more is I have an older version and if you were to sneeze on the pivots, they squeek. So the mud and water are a PITA and I try to keep it as dry as possible. The new versions don't have the same problem, thankfully.
For me, living in NOVA, I think the Nomad is too much bike if you spend the majority or your time locally. Before I moved here, the Nomad was definitely on my short list of replacements. Down the road, I can see it being a 2nd or 3rd bike. It will come down to preferred ridding style and location.
I'm not interested in a 29er v 26er debate as they both have advantages and disadvantage but have you considered the Tallboy? It's a great all around bike and 29ers work well in the local terrain.
