I'm a fan of the big bag. The first time you have to stuff an entire deer or similar in your pack plus gear, you may very well start to think maybe the small bag daypack on kifaru frame is a silly idea. I sure did.
I tried a 3500 bag system on my kifaru frame and it sucked for me. Great unless I killed something. Now I run a DT1 bag all the time. Cinches down small enough when empty it's no issue.
