I use Rok Straps and rode 19.000 plus miles with two gear bags strapped to the top of each pannier. I put two straps on each handle and crossed them over the top of each bag. I rode from Kansas City to Alaska by way of Maine. They Never moved. Both are 35Ltr bags.
I can tell you that if you haven't tried Rok Straps, you are missing out. I have six pair now. I have no idea how I did without all those years. Broken bunggies. Holes rubbed into gear. Snapping back into my face. Almost losing my bag - after all my gear fell out on the last 10 miles down the road. I then got regular straps and went that way for a while. Then Rok came along. I am not joking when I say it's a game changer. I have never had one fail and I do tend to put things to the test.
Try them and let me know how it works for you. If you don't like them, I'll buy them from you.
To me, the best kind of trips are the ones you planned on the way, allowed yourself to change, and maybe didn't end up where you expected. Klay
