Should i go with a speedy or a BH? I'm 5'7" and mostly carry shoulder bags...i was pretty much sold on the BH, when i started thinking that it looks like most of my other bags... which is good and bag. It's good b/c i would probably use it alot, it's a style i'm comfortable with... But it's bad cuz part of me it getting bored of shoulder bags, so i'm wondering if i should go with a speedy... if so what size? Your feedback will be greatly appreciated! Let me know what you think regarding size, comfort, and how much you can actually fit into a speedy..
