The Diane looks really nice but, for me, I'd have to get a different strap as I don't think the casual webbing style really works with it. Seeing your photo of the Odeon PM reminds me of why I didn't keep mine. It is really awkward to access it because of how flat the top is and I was always scratching up my hand on the zipper. You have to kind of pull it away from your body to get your things out, which was too fussy imo. Glad you kept the Metis - it's a great choice.
