arkel gt-18 huge zip.

i tried ortlieb as well today, it was a little loose, but i agree with jur's approach. for the ortlieb downtown and office bag, looks like the space between bottom hook and top loops is too short to fit the crossrack. i'll try again in a month or so when i get to ortlieb dealer, to see if i can come up with creative way of fitting it onto my bike

i'm starting want more convenient access rather than waterproof bag. so considering teh arkel gt-18, the carradice nelson longflap, super c saddlebag, maybe novara commuter.
