I have been debating between a Batignolles and Mezzo for an easy-to-wear, carry-everywhere bag. I finally got the Mezzo and I love it! I'm not that worried about the vachetta bottom but I guess I'll see how it wears as I use it. When I have had bags with piping on the bottom I used to worry about corner wear and the piping all the time. So here is my question: Which do you worry about more: Bags with vachetta bottoms or piping on the corners?
