I see this thread is a bit dated but I thought I'd add my thoughts. Like derekp1999 I wanted a harness that was a "pouch" that the binos were not connected to. It makes it easier to pass them to a hunting partner, or put them on a tripod, etc. After a bunch of research I decided to try both the Alaska Guide Creations pack and the Oregon Packworks Binobro. The AGC pack has become my favorite. I thought at first it might be too bulky but it hasn't been and I've found it incredibly handy to hold a few extra items like a gps, snacks, tripod mount, Petzl E-Lite, and my rangefinder even fits in the front pouch. I do wish the "basement" on the AGC was more like the Binobro as the smaller zipper makes it a little more difficult to access but it's still nice to have. While the BinoBro is a more compact, no frills unit that works quite well, for most things I think I prefer the AGC. I do like how the BinoBro opens away from my chest rather than towards it but that's a pretty minor thing. Both systems work well and fully enclose/protect the binos. I guess it just depends on your preferences, I didn't really know my preference until I tried both of them.
