Any rpm where the engine & drive train is running smoothly is OK. Mine starts to get into the resonant point of the drivetrain around 800 - 900 rpm but I have idle adjusted to around 1600 so I don't ever feel the rattle and vibration of the resonant point in normal operation.

What is the lower idle ranges? I can pretty smoothly idle around 1200-1300, even a bit lower. I usually don't stay there for long as it seems I recall mention Tracy's PSRU may not like it that low. I usually idle around 1550 - 1650 rpm. It doesn't seem to matter much regarding temperature raising over a somewhat extended period.
