You should defenitly check out lowepro pror unner aw series! I have the aw 450 and it carries all of my gear with no problem ( its also possible to mount a glidecam and a tripod on your back!).
Its much more expensive but you get a much more solid bag i believe (mine is rock solid, seriously) But if you take a look at the aw 350.. You get space for all of your equipment and you have rest space that you can use for example for an extra sweatshirt for the colder days and more!!
Hope this was helpful!:)
