i saw the thread on the fastpack350 and it became an eye opener for me. currently i have my tarmac velocity 7 and crumpler 7M bags. i find most of the time, i'm using my velocity 7 with my 5D2 gripped + 24-70 & 580EX2. i like the 7M bag, but only use that when i'm carrying 2 bodies and my 70-200 out. but by then, the messenger bag style puts too much pressure on my shoulder.
i like the design of fastpack350, but i don't need that big of a bag, so i'm thinking maybe the 250 will work. i like the idea of not needing to take the whole backpack off to access my gear and it sort of acts like a sling.
so besides the fastpack, which other brands makes something like this? if i do carry a laptop, it'll be a 12" or maybe just a touchpad. so having that feature for the laptop does come in handy.
let me know which ones i should be looking into that is a backpack style with side access. thanks~

it's heck alot more in price.. but really like the design. maybe i'll just have to wait till price drop.. i hope.
