Lately I am thinking about getting a neo cabby and deciding whether I should get the GM or MM. Since I am might use it for school (for my A4 folder, azur pochette assessories, a water bottle, a wallet, keys), the net weight of the bag is one of the fact I will consider. Can any neo cabby owner weight your neo cabby? I know it is a little odd but it should be the most accurate reference. BTW, I am using BH for school and I just love it!!!!!!!!!
