One more vote for the Stumpjumper EVO - it is a fantastic bike in both wheel sizes.
It might not be enough bike for the thread-starter, but sure is fun even in a bikepark - at least on the flowier trails.
I am waiting for my 2014 26" Stumpjumper FSR Carbon Expert to come in. (ridiculous naming scheme btw.)
I testrode the Enduros 26 and 29 and the Stumpjumper EVOS 26 and 29" back to back. No matter what, the 26er SJ Evo was exactly my cup of tea.
It is just so much fun to ride.
It was light, nimble, yet confidence inspiring even in the rough. It was incredibly easy to throw around and really DRIVE the bike. The 29er adds a big chunk of rollover and makes a lot of obstacles pretty easy to just charge and be done with. But in really hairy stuff, I also feel that the more maneuverable bike feels more "able", at least to me.
I think both wheel sizes work. Both have their place. Mid-season we´ll probably see a 650B version, which probably also will ride great. Don´t really care about that though.
When the new beast arrives, I´ll part with my 2011 SJ 29er Comp, which also served me very well.
But the small wheels, stellar carbon frame, Pike, 1x drivetrain, a LOT less weight, better stiffness and other nice details just feel great. (at least the loaner bikes did in the Austrian Alps).
The Nomad is a great bike as well. Might be almost ideal for the thread-starters need. I don´t like the slack seattube though. I have long legs and ridden several "slackish" bikes in the past. They are rideable and inspire confidence, even with an XC-saddle height, but steeper ST angles just make my climbing easier and I get less lower back pain, because I don´t have to constantly sit on the nose of the saddle to keep the front-wheel down.
