I didn't like that i had to go 'under' the flipped back flap to get my flash stored in the back pouch. I might buy a TT pouch to store the flash at the side/front.
yeah, that's my one gripe too. I wish the accessory section was a zippered compartment behind the lens tubes, or that there was another way to get to it at least once you flip the lid over. Maybe it could have been on the inside of the lid?
But be careful with the additional bag idea, there's no loops to make that easy on the LC3? The retros have great side loops though.
