Thanks for the replies. Nick, bearing in mind what you said, I have been looking at the SW Motech stuff as they seem more flexible. Adapter kits are available to fit a standard rack to fit virtually any brand of luggage (or so they claim!). So I am now looking at their "Quicklock Evo side carriers" with the same idea in mind. They seem smaller, more unobtrusive and cheaper than many other brands: �222 (ish) including the H&B adapter (I have some old H&B "alu standard" panniers), as compared to Metalmule �306.37; Touratech �238.51 for example which are brand specific frames. Anybody use the Quicklock Evo system? Thoughts?
