Are you just looking for a harness or are you looking for a bino pack? I like the packs substantially more than just a harness. I've used one of the Alaska Guide Creations, it was big and stuck out farther than I liked, not a bad option. I've used FHF Gear's older one, not the FOB, for a long time. I liked that quite a bit and I liked its compactness. I recently went with the Stone Glacier, the Skyline, it's nice very light weight and comfortable. I like the front opening feature much more than the others that I had. The one issue I had with it, while elk hunting and carrying a pistol attached to the harness with a Razco holster, was the clips on the harness would come undone if I jumped off a rock or something or even ran a little bit and got things bouncing. I've yet to try anything to fix this but that's on my agenda before this fall.
I've heard really great things about Marsupial's bino packs too, but haven't tried them yet.
