Once again I am on a quest to find the perfect bag for my rig. Here is the recipe; 8x10 Zone VI ultralight, Gitzo 1228 and ball head, maybe six 8x10 holders ,darkcloth, changing bag, film and meter. All this must fit comfortably in a bag that I can check on and avoid the hassel of lost luggage. What are you using and what do you recommend. F64, surplus Alice bag or perhaps you have uncovered something else that meets my requirements. All other necessities, clothes, trail mix, cadbury chocolate, (yes cadbury chocolate is more important than clothes) go in a breifcase that I also can carry on. I fly about 6 times a year within the States and to Europe. Forgot to mention, the bag must be extremely light because I carry it around for about 12 hours a day. I await your wisdom.
