I did a lot of reading & pic viewing before I decided on the Mini Marley. I am 5'2" & the full sized would hang low. The handle drop are longer & with the size of the bag, it will make it end really low. Personally I like the way a Nikki hangs & where it stops for my height. I would probably have a hard time fishing things out of the Marley esp in a squishy leather. It would seem bottomless. So I went with a Mini Marley, size is good & comaprable to the MAM somehow. It definitely holds more than a Mini Nikki. But coz of the size, there is not much room to be all squishy(which I have come to realize after a few days of carrying it). That Black Mini Marley on bonz, I think it is the smoothness & flash that makes it appear shiny-ier than it is. I have a similar leather bag or so I think is( (Teal) & it is not as shiny as many of RM leather(fig the recent pebbled ones, in fact all the recent pebbled leathers). It definitely is not as matte as Dove Grey.
On the subject of too many greys, I have way too many blues. Probably 5 bags? It is just a colour I like for bags now & I don't think it's too many coz I get a lot of use out of them. Like today, the top I wear just works better with Bright Royal w Brown BW MAM. It will work with EB Mini Marley or even Royal Avalon but the MAM col works best with it.
