Love my Bbee, currently my favorite pack. I've had it for maybe a year now and used it for commutes on the bike, running, sometimes shopping and other city errands, and drag it all over on long Greyhound rides. Like Craig I'm always surprised at how much I'm able to stash in there. Very comfortable, zippers are so easy to use on the go especially 'cos it holds its form well. Definitely tough construction.
I like the mods! Did you reinforce the daisies on the inside? I could see trying something like that just to run some light shock cord to compress stuff and stash a shell.
