Can we assume both systems are geared for the same approximate speed?

Otherwise, the only thing that stands out to me is the new system has a smaller motor pulling a taller gearing for not much difference in weight.

That is correct. Wondering now if I should have gone with a 1515 instead of the 1512. The gearing though did not change. I left the same pinion on, so speed might have dropped 1mph....but not much.
