The GM seems a bit overwhelming.. I think the MM would look perfect on you. The MM holds quite a bit if that's your concern. I've just taken a quick picture for reference.. This is probably the most I'd ever carry in any size NF, because of the weight. There's a Macbook, textbook, thin study guide, duo-tang, long wallet, phone, iPod, some make-up, lotion etc. Hope this helps with your decision.
