I need a bigger bag. I want to carry this kit: Body, 70-200L, 24-105L, ?maybe a wide angle? or a couple of primes, 580ex flash, cards and a tripod or monopod. My prefered mode of transport is to cycle so it's going on my back and not in saddle bags but I do sweat like I've been rained on. Amazon doesn't have a great choice and what's there isn't really getting thumbs up. What do you boys n girls rely on?
