Interesting opinion, and interesting fact -- I assume -- about Singer and Herse using 700C with narrower tires for "go fast rando machines."
Regarding the moment of inertia, I don't doubt that the feel of certain combinations of diameter and width correspond across the spectrum; it's just calling these "best" that troubles me. Again, my main reason for doubting such "optimums" is that my own handling benchmarks are 559-wheeled or 571-wheeled bikes with tires no more than 30 mm (I'd happily go 32 but the Elk Passes max out on my rims at about 29 mm; to be precise: on 19 mm outside rims, 27 mm; on 21 mm outside rims, 29 mm; so I daresay they'd reach 32 on, say, 23 mm outside rims); but ~28 mm feels just fine for pavement and light dirt/gravel, and certainly the bikes handle superbly to my senses. At any rate, I like their handling, even with 22 mm tires, better than say the Ram with 29 mm tires, and certainly better than the Sam with 33 mm tires. I got rid of Ram and Sam in part because handling was not up to what I expected from my 26ers. And once again, I can certainly tell the difference between a 26er mtb with light wheels and a 29er with light wheels, but I can't say that I prefer the 559 X 50-60 to a 622 X 50-60, still less that one is "better".
