Any of the higher end packs will do fine for you, it all comes down to how much you want to spend and what style of pack you prefer. If you want a pack that will last longer than a few seasons and be (relatively) comfortable hauling meat, look at Kuiu, Mystery Ranch, Kifaru, Stone Glacier, Exo, Seek Outside. I prefer the Kuiu pro system because of the organization and style of the packs. I really don't think you can go wrong with any of them. I do highly recommend calling whatever pack shop you end up going with to talk with someone about sizing. For instance, when I had a Mystery Ranch, I ended up needing a smaller belt when I was firmly in the size range for a larger one. I also recommend really spending some time learning to properly fit the pack to you.
As far as a good pack for your wife, let me know when you find a one.. I have a similarly sized lady but its tough finding a good pack with a shorter frame. I've hear the Kifaru MiniKeg (Name?) is a good one for smaller framed people.
Good luck!
