I've had the Icon, AP 2, Kitchen Sink, and I just bought a hardshell from the vault. I like them all but I carry a bunch of crap with me, so I had to adjust the amount with each one. The kitchen sink was the only one that could carry it all. I went from the icon 1 to the AP 2 because the icon didn't have a computer sleeve. I got the kitchen sink just because I wanted one, but will all my gear one of the side pockets started to come apart at the seams. So far the hardshell is working out fine.
