Sorry if I keep obsessing but I really put a lot of thought into the purchase of my new bag. I thought I had my sights set on the LV Batignolles vertical or Popincourt Haut. Now the logical side of my brain is kicking in and wants the Damier Papillon 30 due to its weatherproof exterior. I won't have to worry about water stains, marks, etc. But, on the other hand will the barrel shape of the Papillon be too awkward? I really like the Mono too but wonder if the vachetta is just too much work to keep up (even though I've done it w/ my other bags but I now want a low-maintenance bag). Curious as to your opinions??? What are the pros and cons of both exteriors?
