I have a model very similar to this. it was just this week I was entertaining the idea that I need to make other arrangements in as much as how I carry goods around. Maybe at 52 I'm just a lazy git that isn't used to carrying this gear? I don't know....
But when at an airport with 2 pro bodies, 17-55, 10mm, 70-200, 14-24, 24-70, 2-SB-900, and the few assorted items needed to keep me firing .... This is like hauling around a small child. So IMO, if you're doing anything close to a travel, with near as much as listed.. I'd be either re-thinking the whole 'backpack' thing and entertaining a more logical solution.
