If you had to pick just ONE bag.....

Well if I lived somewhere where it NEVER rained and I didn't have to worry about vachetta....then it would be my new Stephen!

if I had to worry about rain...then probably my boring ole Damier papillon!
 
Either BH or LH. I'm leaning towards the BH, but if it were my only bag for a whole year, I might need a zippered bag--in that case, it would be the LH.
