i actually ordered this but then cancelled it. if i were to get it i would definitely get the mm. with an open top bag, i think the pm puts your belongings too close to the top. jmho. the first time i saw a photo of this bag i loved it, but ultimately i decided it was too structured for me. i actually prefer the lines of my azur nf. i also think it is pretty expensive. i have the ikat from last year and this one is hundreds more. having said that, i still think it's a pretty bag. best of luck if you decide to get one : )
