I hope the guy got his doctorate and is happy with that; he sure didn't shed any light on the perennial saddle debate.
Call me unimpressed but I like a saddle that is comfortable and efficient, wide and narrow enough for me alone. Your personal requirements are not mine. With this in mind, I will continue to commute, race and tour on Brooks saddles, despite what the marketers, fashion police and clueless researchers tell me I'm doing incorrectly.
All bike products are a compromise designed to appeal to a cross-section of the buying public, at whatever price point. Designers with a more practical bent than Mr Mann have spent a century trying to improve on Brooks principles, without success. In actual use- and who can say how many miles Darrell is clocking up this march?- the compromise is simple enough: if it ain't comfortable, you can't ride. Many so-called improvements to cycle products fail to appreciate this truth.
