Thanks for the responses guys - I should have listened to my own advice I give to new members, TRY IT OUT IN STORE!!!
I tried the fast pack and it fits my stuff but offers less "padded" room than the 302 (and its more expensive)
I tried th 302 but it felt really odd on my back since its on an angle, and even though it offered more padded space, if I bought more gear (say a battery grip) Id have to get another bag or, get a really tight fit.
so I went with the Pro runner 300. the most expensive, coming in at $179 Australian at Teds, but it fits everything and I have space for a grip and maybe another lens and so much other bits of storage space, and I didnt realise there was a front pocket LOL, jsut saw it now.
Anyway, thanks for the recomendation of the fast pack, it was just as expensive as the pro runner, but I didnt need that extra space at the top, just not enough padding to hold things in place, so things move around too much up there. Im kinda all for camera bags that have some serious padding - Im too paranoid, I work at a school and I got crash tacled by some kids and I landed on my backpack, and I was glad I invested in Lowepro in my first bag. So when I checked my gear, the only thing that got damaged was my business cards and it was like nothing happned to my gear. If I had a fast pack, Im pretty sure the top section would have collapsed onto whatever I had in there.
Thanks again, This is a really great photographic community.
