Time to chuck the Rohloff in the bin and get a 543% Kindernay?
I will stick with what I know works, they have been building Rohloffs for over 20 years, mine is now 8 years old.
Plus, I just ordered two more rear sprockets for it and have about a decade supply of oil for oil changes, so I'm good. Plus, I can brag it has a wider range than your 1X system, plus has two more gears.
My next tour will probably be with one of my derailleur bikes (3X8), there are advantages to derailleurs and advantages to an IGH.
