I've been happily using Lowepro Slingshot 200 and 300 backpacks, depending on how much I want to carry, when walking or hiking.
But I've found that, although I like to combine bicycling with picture-taking, I don't particularly enjoy riding with a backpack loaded with camera gear. So I've been imagining that maybe it would be preferable to use something like a ThinkTank belt combined with a case for my 30D and one for my 70-200 f/4.
I'm wondering if anyone has tried this kind of set-up and, if so, whether it's comfortable and convenient.
