Don't forget about Auto-route. You can put multiple devices in the rack (not connected to anything) select them all and they will auto-route automatically. Create a Thor, Pulveriser, and Echo and they will be auto-routed in order - a Mix Channel will even be created and attached for you!
To change existing routings, you can choose Disconnect Device first. I've been routing this way more and more to avoid patching issues like the stereo cable issue. For example, if I have three devices hooked in series and want to change their order, I select them, choose Disconnect Device, arrange them in the desired order and then choose Auto-Route Device! Once you get used to it you don't even need to flip the rack to make and re-arrange basic connections. Worth checking out IMO! :-)
