We go to the trouble of increasing spark with after market coils, and then put resistance in the wires and plugs. To make matters worse we get electronic ignition modules whch increase the dwell and put a further burden on the coils. Then we ratchet up the alternator output voltage and really put the screws to the coils, which are stuck between the rock (alternator) and the hard place (increased dwell).

All good points (pardon the pun!). On the one hand, once the engine is properly timed and with a cap and rotor change every year, the spark is consistent and steady, the ignition is maintenance free and suffers no steady decline with deteriorating points, and the engine runs cleaner. On the other hand, when it fails it fails completely. Like most things, I guess it's a matter of taste.
