Just done the rolling resistance calcs on that Schwalbe Superlight. Crr is the same as a used Challenge Crono in 22mm, a good bit worse than a Vittoria Crono in 20mm.
To be honest it's better than I thought as under closer inspection I now suspect it's got a vulcanized inner tube like the Tufos. Certainly sounds hollow when you pump it up to a zillion psi and then drop it, so likely not latex after all. You can't feel an inner tube in it.
