Regarding the pinkbike data - I wasn't using that as a point of argument in either direction - I agree with you both regarding the results (not being conclusive), but the data itself is valid. I think people should (as I usually recommend) ignore the article text, and only look at the dataset. I do feel it tells a different story to the marketing-driven conclusion - the numbers were pretty close.
My point was that a few people posting here who strongly oppose change (it's always the same names) have rarely conducted testing that even remotely approaches "valid", and having made the same mistake in the past (and corrected it recently), this time I'd like to reserve judgement until I can test things properly myself again.
For anyone interested, my brief conclusions on 650b was that it not only faster (times), but made riding long rough runs substantially more enjoyable due to the big reduction in force transfer to the rider. I also found that the advantages were significantly more pronounced when only running 650b on the front (with much less difference noticeable on the rear) - so for those who aren't bound by racing rules - running a big wheel just on the front can make for an enjoyable compromise between the different options. On the downside I also had to make some compromises to keep my bike weight the same which I'm not happy about, and braking force went down noticeably (from 26 to 650) so I had to switch to a more powerful brake as well. The net result was positive however and I hope that more parts choices open up in the future to reduce the compromises.
Given the experience I had trying 650b on both ends vs. just on the front, if I try 29 for DH I'll probably try it just on the front first (and reset geo), I have a feeling my results will be similar to last time.
