The NF is my favorite bag. My vote is for the mono. The azur is harder to keep clean (believe me - if you've seen any of my posts about cleaning interior canvas). The DE is fabulous but I read too many horror stories. So, I got the speedy 35 in DE.
Thanks everyone, learning a lot from all different comments?
Mrs Kiwi, how long have you had your azur and how is is it holding up?
I have had mine just over a year. She looks perfect...but then again...I rarely ever use her because I don't like dark/dirty handles or leather on azur. She is almost strictly just to have and not to use.
