Hi all, hoping for some help here. My wife has a LCB which she loves, but would like something smaller when she doesn't pack as much - something more like a casual purse. I'm undecided on the MCB vs the SCB. It's hard for me to know exactly what she will be carrying. Is the SCB too small for everyday use? The MCB too close in size to the LCB? Any help would be appreciated. Sorry I can't be more specific on what she will be using it to carry. Thanks.
