I'll have to look through the archive, but in the mean time I'll be pushing a car tire with my pinky.

the only place you can really feel extra weight on a bike is in the rear tire/wheel.. you have to pay for the weight there twice you have to spin it up and carry it with you the 26er has the advantage here.. after acceleration the rolling resistance comes into play. which may favor the 29er.

I'm not even going to look up the archive thread, because I'm sure you were proved wrong and have forgotten already.
