Forgive my ignorance, A/M ignition

Good point, but wouldn't the system be more reliable with parallel circuits?
If, for some reason, you get a misfire, a series twin tower coil would prevent both sides from firing.
If you get a misfire, in a parallel system, at least one side would end up firing...

Side note...
KDR used to sell this ridiculous system which eliminated the trailing spark plugs and fired everything on just the leadings.
If the ignition system were in series, I'd be scared to run it like this...

The twin towers are a bean counters solution to reduce the number of coils
required for the ignition. They should have used a single coil for each leading
plug or for each plug for that matter.

Anyway, I run one TFI coil per leading plug and it runs very smooth, no trailing.
Until now I wasn't sure why but RETeds' explanation was an ah-ah moment for
me once I read it. Makes sense to me.
