To all you 29er's out there!

That's really course dependant, sometimes that will be the case, sometimes not.

We're talking XC here...you will pretty much ALWAYS have more flat and downhill sections than super technical sections

Smaller wheels need extra acceleration because they don't roll over stuff easy? Newtonian physics does not depend on obstacles in a forest somewhere, less weight = better acceleration, basic physics. But it's a given that the 29er wheels will roll over stuff easier which I (and many others here) have said many times on this thread anyway.

You missed the point here...Because smaller wheels don't roll over obstacles as easily as bigger ones it means you will be slowed down more often and hence will need to accelerate more often to get back up to speed

Lighter bikes, less rolling resistance and no energy being sucked away by suspension (if we're talking suspension MTBs here) would be what i'd put that down to.

No, I'm talking about rigid MTB's here, with narrow 26" tyres

Probably agree with you there, not sure of the relevance of this point though.

The relevance of the point is that you were claiming earlier that 26" wheels will be quicker on almost all courses 'due to being more nimble and having better acceleration'...I'm saying that they wouldn't, so I'm surprised you're agreeing.
