What is the deal between tall and short caps? I assume they take different rotor buttons.

As long as the rotor is making contact with the terminals and sending the spark to the plugs, the electricity doesn't know the difference. Why would dizzy cap geometry make any difference to the spark?

Not saying it doesn't, I'd just like to understand the reasoning behind it.
