I used a mainframe with 2 batwings to haul my lone wolf assualt 2 and some cut down lone wolf sticks all last season. It worked pretty solid overall for the hunting side of things. I started doing a lot of weighted pack training and found that when I get up to 40lbs or more in the pack it just really didn't carry great for me so I recently ordered a Kifaru Stryker XL and frame that I'll be trying out for this season. If the Eberlestock fits you well and carries weight good for you I'd say you'll have a perfect hang and hunt pack. Between the space inside the batwings and the space you can stuff extra layers behind them I never had a problem hauling out everything I needed for a hunt.
