I already have a canvas Domke F-2. I want to acquire the ballistic nylon equivalent. That would be the F-2B. However, Domke also makes the J-2. The J-2 seems to have an identical layout to the F-2 (unlike the F-1x/J-1, which are different). It's heavier though. So what's the difference, apart from the slightly longer flap (which I like).
Does J-2 have more padding than the F-2? I hate padding. I want the least padding possible, but I like weatherproofing.
Thanks.
