So I'm looking for a decent bag to take on an excursion across china and I'm pretty sure that I've narrowed it down to these two bags. Kit wise I'll have the 7D, 24-70, 17L, 35L and 135L with 4 batteries and a slew of memory cards with an Epson P3000 and MBP 15". The burton definitely seems roomier and possibly a little more weather resistant than the crumpler but comfort wise I've found crumplers to excel in this area.
I'm going to be covering somewhere around 4000km's via trains, buses and hiking up multiple mountains on this trek so I also need something that can hold a water bottle or two, some snacks, power bars and take the punishment.
Anyone done some really long treks and put either bag through some good punishment?
