Thanks for all your thoughts chaps; appreciated.

I do like the idea of the towbar/rear mounted rack combo but is going to set me back around £500 which is by far the most expensive but think provides the best solution (no drag, reduced wind noise, ease of access & removal, leave the roof free to potential roof box, etc). We'll have to see how full my pockets are feeling when the time is right.

Reaching the roof on the QQ+2 is a pain in the arse as I'm 'average' height, I can't reach it easily when washing it (rarely admittedly), so the thought of lifting a bike above my head & onto the roof doesn't excite me. But, for the cost, and the occassional use, shouldn't be ruled out.

I'll think on...
