So I finally got a chance to get out and take this rack on a nice long overnight, and the rack performed very well even when loaded to max capacity. Everything stayed in place very well my only concern is that certain bags will fit better than others. The swooping legs on it make some of the hard plastic backed bags not want to sit perfectly against the rack and bumpy dirt roads can occasionally give you a little buzz from a spoke touching the corner of your bag. Anything with a more rounded profile works very well though. All things considered though, the rack performs very well and never gave me any signs of flexing.
