...i posted about this in another thread, but i'm thinking that might not be the best place for it. anyway, i've been researching panniers for extended touring. i've pretty much settled on axiom, but i'm unsure how much pannier space one really needs. how much space do you typically need on a tour...

...i was thinking of getting a pair of Axiom Kootenay's for the front, and one Axiom Champlain in the rear (something else will be taking up the other rear side). but if that's more space than necessary, i'd rather go with something like one Axiom Laselle, or Axiom Typhoon in the back, since it seems like it'd be easier to manage...

...any thoughts? am i being overly stupid in my approach to this?..
