I have an Ellsworth Epiphany, and an Evolve. Both built up pretty similar. The 29'er does not leave the ground the same way the Epi does. The way you hit certain things has to change depending on which bike you ride. Contrary to what some of the 29'er guys will try to tell you, the 29'er isn't some revolutionary thing that makes all others obsolete. Yes, they get "slightly" better traction, but it's not so over the top you will be blown away. Yes, they do tend to roll over things easier, but that doesn't mean you can totally disregard line choice and never have to lift the front wheel. And yes, the do tend to hold speed better through certain sections. But in other places they suffer. Get a frame of bike that isn't set up right and it won't be as agile. It will be harder to get going again in the tight twisty stuff. Every bike has it's trade offs, try one and see what works for you and the way you ride.
Sandpine, you don't ride hard or aggressive. I'd bet those wheels you have wouldn't last more than a couple of rides for me.
