With your collection, I'd keep the Noe BB. I have the Noe BB and I love that I can crossbody it and I bought another strap for top handle and it's the size is perfect for what I need.
With my collection, it's so hard to pick but I'll just go with the Pochette Metis since I have 2 of them, black empreinte and reverse mono. The black empreinte is more subtle than reserve mono and I feel I can use anywhere without the monogram being all up people's faces .
I'm breaking the rules a little and say I have 2 for 2nd runner ups...my Keepall 25 or my Cruiser PM. Needless to say if I have the will power to only pick one, I wouldn't have an LV addiction, LOL.
