I'm no expert on bearings either
My only observation is that Southern rolled trains (until a few years ago) regularly up and down Saluda Hill on a +4% grade with roller bearings.
Yes they put on extra motive power for dynamic brakes. 611 took it with 3 cars as I recall.
As I am told from live steamers (my closest experience) is that properly oiled, friction bearings roll as easy as ball or roller bearings. If so, I see no reason not to use rollers.
My observations for what its worth.
Doug
