The design places the weight over the seat with some transfer to the frame via the Dirt Bagz rack. On the trip described in the linked ride report I encountered some heat issues from the muffler on the first day - a sharp tug on the rack moved the whole deal out enough to create some air space and there were no other problems on this trip.
I've put about 5 or 6 thousand miles on my XC with the Dirtbagz now. No issues at all. I actually found a used set with racks, so I got the whole set up pretty cheap. I have torn the connecting strap off the right one, but that was in a pretty hard get off. (Broke my fibula and ankle) I added a heat shield from Giant Loop to help with cooking the bag that's against the exhaust. I've been lucky with rain, so I can't tell you how bad the waterproof problem is.
I did just add a GL Coyote bag. (They were on sale, and can be mounted over the Dirtbagz racks.)
I'd buy the Dirtbagz again though. Best bang for the $$..
