You SO have to do the Tauerntreffen mate, it's right up your street. There are guys there who out-gadget you in a big way (and that's saying something).
I'll leave it to Jethro or Jules to tell you about the stuff one Z1300 owner had fitted to his outfit.
Seriously, I reckon you'd enjoy it a lot.
Mind you, it's half full of northerners already... one of them had even ridden there on a bloody C90
