Meh. Even trying it with just about the perfect 26" frame to try it with (coming from a tall fork, so it would'nt whack my geo out from what i was used to) I really disliked it. Granted, I think it would have been better had things been steepened up more than by only a degree. IF you are careful about what frame you try it on, and what fork you use, it may work out for you. Me, I really, really didn't like the way the larger wheel handled up front.

Cheque the rest of the 29er forum over there; lots of good info, if you're truly curious. I'm sticking with 26" for my riding. The experience owuld have likely been different on a full 29er or more built from the ground up, designed for it 69er/96er.
