FYI, I just produced a video overview (not quite a review) in which I unpack and repack an F-2, and show the contents from above. It may help those of you considering larger bags.

I love the bag for carrying way too much stuff. I just used it on a multi-day car tour doing photography. Admittedly, I shot out of the car, and didn't schlep the bag around very much. As fully-packed as it was, that would have been a painful proposition.
