I switched over to the enclosed Marsupial harness last year after previously running the Alaska Guide Creations Classic bino harness. I definitely prefer the Marsupial harness over the AGC, it is much slimmer and seems to hold tighter and more securely to my chest when moving around in the backcountry. I run it with the range finder pouch as well as a side pouch and have never have had an issue with it getting in the way while drawing my bow. Like others have mentioned above the front bow hanging hooks are nice for a throwing up a quick glass without putting down your bow, but are not suitable for holding your bow while walking.
Whatever harness you end up getting I'd recommend shooting while wearing your bino harness, you'll soon not even notice its there.
