I couldn't find a camera bag to fit my tastes, so I ended up getting a bag geared towards snowboarders and skiers. It's great because it has places to strap skis onto the bag (tripod anyone?) and it has access to the main pocket from the front or the back so I don't have to set my straps in the mud to open things up and get to my camera.
For internal dividers I went with TrekPak and they are absolutely perfect.
So, unless you find exactly what you're looking for, don't get too stressed with camera bags. There are literally hundreds of hiking bags out there that might fit your needs and TrekPak does a good job at handling the rest.
This entire thread reaffirms my faith in this forum's ability to lovingly overthink their gear needs.
So glad I am not the only one.
