All sound like good options. Is the black Diorever in taurillon or the new grained calfskin? I prefer it in taurillon.
My Diorever now is Taurillon also so I would have my SA get me the same leather type. Most likely I'll keep the Dioraddict in gray as I'm also eyeing a couple of Celine bags that would fill the void/need for another Diorever.
