fyi - some of the Wilderness Pack Specialties' packs will fit on a Molle frame - as will their load hauler sling.
www.wildernesspacks.com I bought one of their (Molle) frames and load hauler slings several years ago. it carries reasonably well, but I am short (5'7") and the frame probably doesn't carry as well for taller folks.
I've since bought a military-issue pack bag from Ebay and fit it onto the same pack frame, and it fits over the load hauler sling.
not as light or nice as my Kuiu or Outdoorsmans set-ups, but hundreds of dollars less.
fyi - the Molle pack, with a Wilderness Pack Specialties' load sling, makes for an inexpensive and handy frame pack when using pack stock, because that pack frame fits inside my panniers, whereas my Cabelas pack frame is too long to fit inside the panniers (when empty).
good luck with your search. -spfarr
