Photobackpacker has officially retired as of one year ago, and presumably is out somewhere with his large format kit. Nice guy. He made a really slick film holder carrier/organizer for 2-slot sheet film holders, too.
I agree with Buckshot. F-stop makes great bags, IF you fit the bag. I have the Satori, it didn't fit well for long carriage or heavy load - I could do it, but it was wearing me out. Turns out that the standard fixed F-stop harness has a torso length of 18" to 19". I didn't know much about fit, not having done camping since I was a kid - turns out that my torso length is 14.5" to 15" . No wonder. For camping, an extra-small women's Osprey pack set to minimal torso length (~14.5"), with wide zipper access to main compartment, does the trick. F-stop is making a fixed 15-16" torso length women's bag based on the Loka, but hasn't got stock yet.
Thanks for the Lowe Pro Rover suggestion (16" to 19").
Mindshift's First Light, a brand new design, has adjustable torso length, but I couldn't get the Mindshift customer service rep to tell me the range.
Even a 16" pack should ride better than a 19" pack. I don't think that there will be photocentric packs with 14.5" torso length made unless I commission one from a custom pack maker like McHale. Big bucks.
