I'm a bit ambivalent about the S24o thing - on the one hand, it's a thing that people have been doing for donkey's years without the need for an acronym, so Rivendell stamping their name all over it and claiming it is a bit annoying. On the other hand, it's obviously encouraged you (and probably many others) to do it by awakening them to the idea, and Rivendell are hardly a mega-brand using it to put their name out there.
Anyway - lovely ride and report, G.
