Since you seem to be OK with larger and heavier packs, you might look at the Mystery Ranch Terraplane. It looks suspiciously identical to the long-gone Dana Designs Terraplane, which was The Pack way back when. I had one, and loved it (except for the 8-pound weight) - it's advertised claim that it made a 100 pound load feel like 60 was true. (It was a couple of years before I figured out that, for the trips I took, I would never carry 60 pounds, let alone 100. )
