Hi, I have a Lindy 30 and a Toolbox 20. I use my Lindy a lot more than my Toolbox. I find the Lindy more spacious and much easier to get things in/out of the bag. For the Toolbox, you have to unlock the bag each time you need to access the bag and you can't leave it unlock because then everything will fall out. As for my Lindy, I leave the zippers open and just lock the bag by using the turnlock. That way I can access the bag from the side. I'm 5'4, I find the toolbox 20 looks a bit small on me, Lindy 30 is just right, recently I tried on a Lindy 26 at my home boutique, it's very cute. Maybe when you are in Europe, you can try on the sizes first before deciding which to purchase.
