......My older MR Dragonslayer just has a framesheet vs the new ones with the X frame suspension, and even with a perfect fit, I still have to watch how I pack it. Carrying stuff attached to the outside that has any weight to it can turn into a miserable experience, especially. I've done it with a rope bag a couple of times this year, and it seriously degrades the comfort, especially if I pack a bunch of hardware in with the rope. Does much better with everything inside the pack.
The newer Dragonslayer lacks a few features, but I bet with the frame it's a much better pack than the one I have. It weighs about the same, actually a little less, than the Rush 72, too. It's $120 more, but that would seem like nothing if you had to carry a load in it for very far, or very often. Still not a backpacking pack, but as a do-it-all hunting, hiking, climbing, etc.(and tacticool!) pack, that thing is hard to beat.
