I was one of the folks what wanted put a AHBC as pocket in one Qui-Ya (Qui-Ya have better load management than Ute).
I today see this (AHBC as pocket) as is no practical. More pratical is the Qui-Ya or Ute only and NO POCKET. This large load packs will have 90% or more of all things do you need in long terms outdoors. If you optate for a pocket, this (connor or palspocket or tarahumara or tara pocket) will have the others 10% or less of your gear.
When your set your basecamp, if you need make another small incursion that need a pack, so you will leave the Qui-Ya or Ute in basecamp and will load your pocket as your pack. (You will need another harness, or pocket harness, or shifting the harness of qui-Ya or Ute to pocket)
I learned what load carriage in wilderness is a constant exercise and demanding of wisely decisions. Useful things vs weight of this gear vs I want this gear vs I really need this gear.
The final aspect is no how many lbs do you want/can carry in long trekking.
