i've had the large superpro for about a month, and it is a great bag. like you, i had wished for more photos before my purchase (i wonder if all these companies are just worried about leaking design secrets or something), and it turned out that the large size is a bit too big for my current use (commuting with books/laptop). but it will come in handy if i ever live away from a grocery store or laundry mat. otherwise, if you're just commuting the medium might be the better choice. i had also considered the pac street scene, and now might wait for their "mini" size bag to come out to meet my commuting needs. the two big pluses i saw in pac were the padded back and inner tarp lining. the big plus i saw in bailey was the reversible strap.
