If you do go Tubus racks.... This is probably blasphemy on this forum, but instead of getting them from the TheTouringStore. You can get them for a lot less at wiggle.co.uk. and then add some coupon codes to it as well (google for them) and you can it even cheaper. I got my panniers and racks from there and all together spent $190 dollars less than I would have at the TouringStore.
As I said this is pretty much blasphemy because there is a huge following of this Wayne guy, because "he is honest and will answer any of your questions" but I have also got this advice from this forum and no one is to say that the guys at wiggle are dishonest and give bad advice.
