Slightly off topic, but "bundle packing" is suitable for a trip where you get somewhere and unpack everything, then hang items on hangers or put them in drawers. It's time-consuming and inefficient for trips where you need access to only certain items each day, or are moving from place to place and need to pack and unpack often. I prefer using packing cubes, one packing folder, and/or 2-gallon ziplock bags. Much more efficient and I find that using the ziplocks allows me to pack more, since I can squeeze the air out of each bagful.

I'm with the person who said s/he prefers a wheeled bag. By the time I get a maximum-carry-on bag packed, it's far too heavy to carry around airports, train stations, etc. - great shoulder strap or not. Good luck with your decision, the Red Oxx bags seem to get high marks from flyertalkers.
