Honestly, no. My mono bags are at that honey stage but I never use them anymore and haven't bought mono in a long time.
Actually, what DesigningStyle said is right on the money - there is a difference between dirty and dark! I live in LA and Las Vegas and I see lots and lots of LV and have been totally turned off by dirty, black, stained vachetta sightings. Ew.
But I do love to see a vintage piece with nice, even patina!
