Redfacery, I use a fanny pack in front. I don't remember what brand (label is gone). It has worked out well for me. I keep my camera, some essentials, GPS, map and a snack inside. I don't know if it counterbalances my backpack, I've never noticed it that much. I use it because it's just so much easier to get to that stuff.

Good luck BorealHiker.
