I had considered a Rohloff years back.
I hate the jump from 53-15 to 53-17, what is that? 14%? Isn't that the standard jump on a Rohloff? I like one tooth jumps when fighting the wind (cubic) and 3-4 tooth jumps when climbing (linear_ish). A Rohloff would not work for me on a brevet. Touring? Should be fine for me.
