And a proud owner of an F1x, F2, F3x, F4AF, F6, F803 and F806, I have many different bags, all of which are mission specific. I have found that for international travel, I prefer my F6. (The F3x is too small for my D2Xs w/ travel glass, and the F2 is bigger than I want to haul around) In the past, I usually have to bring my laptop in another bag. However now with the new netbooks on the market. (Finally snagged one on my last trip to Tokyo) I'd like to keep it with my camera so I can upload in real time. So, I'm wondering what is the chance of ever seeing an F6 backpack?
