Just be careful. The 30 is very heavy on its own. Add some typical travel items and it weighs a ton. I would try them out in store (even in a diff color) just to get a feel for the weight. I personally cannot use my 30 for anything but basics like a wallet and phone and pochette with little things in it. My shoulder hurts after about a half an hour of holding it up and somehow the straps tend to slide down a little too. I still adore mine, but I would really make sure you are ok with understanding how heavy these bags get. Plus the 30 really needs a bag organizer and base shaper or else it turns into a total puddle.
