I have ridden steep, rough, rutted, boulder-strewn mountain trails, fully loaded on 32mm tyres and it is very tricky. I often wished that I had 38mm which seems to be the modern standard for touring bikes.
I have Ortlieb Bike Packers and Sport Packers with the QL2 system. I was thinking the same thing about the inserts. I rode a very rough road that was steep in places in MT last summer. It was even bare rock in a few places. While the lower hooks came disengaged a few times, the top connection ones worked flawlessly. The bottom hook problem I can remedy by wrapping the racks with cloth grip tape in a few places.
Bike was fitted with 37c Conti Top Contacts. They worked great.
