I got the straps in the mail today, and did some tinkering. It's far from final, but I like them. They're pretty solid straps. Right around Phenix quads in quality. They come with an extra loop and a sternum strap. I hooked the cell phone holder from the stock sling strap to it. I'll need to find a way to get the bag a bit higher up, but it's such a light bag it doesn't really bother me too much. That might change after a full day though.
P.S. In other notes, I discovered that the more expensive bag I found in the above post is the original bag model. The cheap Amazon version that DJ and HB used are just knock off models of the FuL version. So, take that for what it's worth. At some point I'm sure I'll pull the trigger and get the quality version to see how it stacks up.
