I think I'm pretty much there. GS does the touring bit and pretty much anything else that I need, although the K12GT was more comfortable over distance, and way faster on the autobahns. GS is, for me, a bit heavy for trundling along tracks so I got the CCM for that sort of thing. I must confess that if it's just out locally it's now the goto choice. Anything longer, or decent roads and it'll be the GS. Sport bikes and my back don't go together so have never been an option.
