Somewhere near Aguila, Arizona
My 1981 Miyata 1000 worked like a champ on a tour of the Southern Tier in 2017. In retrospect, I should have used Paselas or some other flexible tire instead of the hard-riding Continental Gatorskins I did use.
I very much prefer to use front panniers alone with a small trunk bag or big saddlebag. I think it makes for a much more stable ride especially when you stand on the pedals (which I do from time to time just to give my butt a brief rest). You do need to get the side-to-side weight distribution pretty much even, though.
