Just my 2 cents but if you travel to some far out, or even not so far out, places like I have then your 'SOFT' bag had better be real small. You are completely at the mercy of the gal or guy at the check in counter who just may say you can't carry that on the plane. I don't know about you but checking a soft camera bag with all sorts of camera gear would/could be a nightmare experience. So, small and smaller is best. If I have any doubts then I pack everything into a Pelican 1510. If I have to check it (and I have had to) then I slap on the two locks and pray..... but at least if it arrives at the destination all will be safe. If it doesn't then memories are the only images I will have. Paid up insurance also helps a lot.
