I use my reckoning with a guide lid for everything from day trips to week long hunts.
I usually run a grab it between my frame and bag as a load shelf, I don't really like the one that is sewn into the pack already. Then I will throw another bag of meat into the main bag if I need to carry more and I have the room.
Guide lid up top adds organization for little things like the days food, water filters, gloves, pack rain fly, etc.
Main bag holds my puffy, rain gear, kill kit, etc. Camp gear if I am doing more than a day trip. Love the center zip for access, quick to grab whatever you need and zip it right back up. Run a spotting scope down one side of the pack in the expandable pockets, tripod goes down the other side so it balances out nicely.
The big loop at the bottom of the reckoning is perfect for slipping the cam of a bow into for strapping it to the pack. Have been very pleased with that little feature. The snow collar lid is also really nice because it folds down pretty flat when you're not carrying a lot of gear, but adds a good amount of room with it all the way extended, should you need it. Overall, the pack compresses really nicely for day hunting use. I have a 22 Mag that I bought for day hunting, but haven't used it much in the past few years because the reckoning seems to do both day and extended trips pretty well for me. Maybe that will give you an idea of how at least one person uses the reckoning as compared to your fulcrum.
My opinion on your question, if you don't need or want two packs, why not buy the reckoning, use it on a hunt, and then make a decision on which to keep after some ample, first hand comparison?
