Thanks - that's really interesting. Which route would you personally recommend?
(My interest is that I run cycle.travel, which currently finds this route: https://cycle.travel/map?from=&to=&fromLL=47.390987,8.478737... . I'm not entirely happy with it in this case though - for example, it's not routing onto the cycle path south of the railway on Aargauerstrasse, I think perhaps some of the paths leading onto/off it are rather fussily mapped.)
