Perhaps I'm confused, but the best system for a rotary is ____?

You may not be able to see resistance, a lot of coils are capacitively coupled. It is simplest to observe the direction that the spark takes while cranking.

Actually, you can research the dielectric strength characteristics of air easily. Higher pressure increases the density of the air, which increases the dielectric strength of the air (more molecules to force to ionize).

Breakdown Voltage

Anyway, I am back in town today, maybe I will test this myself tonight.
