Can I join your cult? I'm particularly not fond of spinners here in Europe on brick sidewalks and cobblestone streets--I see lots of people dropping them as the tiny wheels get caught between stones... but spinners are a pain on curbs, broken pavement, etc. everywhere.
Travelpro FlightCrew series are all two-wheeled, even the current FlightCrew 5 models. I have a FlightCrew 3 that's pushing 10 years old and despite a lot of time spent as hold luggage thanks to sharp work-related objects is still in good shape. If the wheels ever wear out, they and the bearings are straight off in-line skates. A gate8 garment bag I recently bought has the same setup.
