City Pack Pro 2 20L + Day Sling 4
Figured I'm probably not the first to do this, but maybe I'm the first to post it.
I was looking for a clean solution for a 1.5-bag carry, and this ended up being the simplest and most practical option.
I usually keep a Nite Ize #3 S-Biner on both my sling and backpack. Using them, I clipped the Hypalon pull tabs/latch points from each bag together.
This is one situation where I wish the DS4 had a detachable strap, but looping it around the bag and side handles keeps it out of the way well enough.
Doing this gets rid of most of the self-standing capability (at least with how I pack it out) going further into the MJ lean, but it's a worthy tradeoff if you don't like the feeling two straps or having the sling locked to the front.
