ignition coil ?

My Square-top Accell Super coil has been running on the same resistor since I installed it, back in about IDK 2002?. No, I do not keep a spare resistor. On one of the spade terminals on the resistor, I installed a a connector with a twin spade on it. If my resistor ever burns out, I would simply move the wires together, and run the coil on full battery voltage, until I got home.
Accell says to run it on that resistor, and since my coil was new in 2002,and continues to function today, I'm inclined to think that running the specified resistor is the right thing to do.
The instructions say that coil is not recommended for over 6500, but mine goes 7200 and more with no hick-ups. And it idles all day as well.
Since I no longer run the factory-type ECU; I no longer run the dual-ballast. In an earlier post Del says that the P4120889 Accel Coil is supposed to run that factory ballast, in series with the Accell ballast. I did not know that, and my coil has only ever had the P5206436 ..... One-ohm resistor.
