Due to an unfortunate incident involving automotive fluids my travel bag of many years is no longer useable. Last weekend after an extensive search, I got a new one which seems to fit most of my (some would say excessive) criteria. I won't really be able to approve until I've  got at least one whole trip with it but so far so  good. One thing I've noticed is that I travelled so long with the old bag it almost became an extension of my body. I knew exactly where every pocket was and could sling it around virtually unconsciously. With the new bag I'm having to think about it. The pockets the balance a lot of little things.
