Whats the best bag setup for 2 up on an ADV? Ive been using the stockers and have found there shortcomings.Thanks to the guys who have picked my bags up off the trail behind me

But a guy can pack a lot of beer in them

Considering the GL Great basin, but it doesn't really look like its usable with a passenger? I like the idea of getting away from conventional panniers.
I would like something that also works well solo. Any recommendations? Do's, don'ts etc..
Thanks!
