I recently started a thread here asking for bag advice (you can read it here)

That thread tipped me off to Seagull Bags based out of Columbus, OH. Their bags get great reviews over on the SS/FG forum, and are very customizable. I've ordered a medium Deluxe bag and have been having a good experience with them so far... they've been very friendly and responsive to my emails. I'll post a review when I get the bag itself.

I will be using mine for a 10-mile round trip commute with a laptop. I don't have a separate laptop sleeve, but have a neoprene case I picked up for the computer a long time ago.

My current bag is comfortable for light loads, but can get uncomfortable with full loads over more than a few miles.
