hmm. It seems that the main arguments are between air resistance (panniers) or rolling resistance (BOB trailer). Which is bigger? I suppose that I could do some calcs...But I don't feel like it. I am probably going to be carrying around 40-50 lbs at most, so carrying capacity is not a real big deal. This is quite a conundrum. I think I need more time to mull.

One other thing: How easy is it to get 16x1 tires/tubes?
