A blanket statement is about an un surveyed population.. is what you want?
Data anecdote:
My flat bars are trekking bars, instead. I'm using a Rohloff hub,
it has a nearly frictionless 2 cable grip shifter.
The Thumbies do accept friction DT levers., square hole stop plate
may be required from the DT shifter Assembly
