Found my answer to the original question I posted.
I stopped by my local shop, Action Wheels, to discuss full suspension 29ers and they allowed me to take home a Specialized Camber 29 Test Bike for the weekend. A nice shop and great people. I rode this bike and my FS 26" back-to-back at my favorite trail. I found the FS 29er to share many of the same benefits of the HT 29ers I have owned. Stable, holds its momemtum, and rolls over obstacles. The rear suspension absorbs the extra jolts from roots, rocks, etc. that would still bounce the rear of a HT 29er around. Surely, anyone would enjoy the bike and those who focus on keeping both wheels grounded and full momentum at all times would love this bike. It's extra stability would benefit those a little shakey going downhill. If my routine was long distances and hours in the saddle this would be the best bike. If I was about efficiency, racing shorter tracks and shaving time off every lap a HT 29er would be my tool of choice. The HT's weight advantage and rigid rear can't be beat for these applications. That said, I smiled the most on my 26" FS this morning making my the answer easy. The FS29er had to roll over obstacles because its extra weight and wheel size made it akward to bunny hop over them. A tug on the 26 and she would leap over the piles as opposed to rolling over. Although it didn't hold its momentum the 26" sprung to speed much faster in the short, tight, twisty single-track trails I rode. In short, the bike wasn't as efficient or stable but definitely more fun. It is all very subjective depending on where and how you ride. What you enjoy.
I agree with Goldsbar, HT = 29er, FS = 26.
