Jared, my wife found those on craigslist last year. They're heavy as all get out. She adores them, and will be psyched to know folks in internetland share her opinion.
Javan, not totally sure what you mean by contouring the pack panel. Wider at the hips, narrower at the shoulders (or something)? One of the reasons I like using a ridgerest (either folded or rolled) in my frameless packs is that it provides just the right mix of structure and flexibility.
I actually only have two packs that have been made from stratch, though both have been reinvented a bunch, and almost all our other packs have been modified in some ways. My Osprey Talon 11 is the only pack I own that is straight up stock.
