So I finally decided on a bag and figured I'd update this thread. I found a local store that carries 5.11 bags, and I spent some time looking around there and settled on
this one in sandstone. I've only carried it for a day, but so far it's much better than the laptop bag I was carrying. Has a TON of pockets and I can carry just about anything I need to. They only thing I don't like is it's not quite tall enough to hold regular 8.5x11 sheets of paper. the flap bends like 1/4" of the paper over when closed. It holds any books I want just fine, but I carry sheet music around sometimes for piano/guitar lessons. That's a very minor issue though and I can probably just stick it in a folder and be fine, so all in all I'm verry happy with my purchase. It was on sale too, so a bag that's regular $95 cost me $72 instead. If anybody is looking for a bag, the guy at the store said 5.11 runs a deal this time of year where everything is 20% off, presumably everywhere it's sold.
Anyway, thanks everybody for the replies, even if I did respond a little late...........
