Tell me about your ballast resistor failure.

The car wouldn't start. Had an old timer tell me to replace the ballast, I did and it ran.

Bought an MSD and never ran a ballast again. Never had the MSD fail me either.

There are plenty of MSD and other aftermarket systems that fail. Yeh. REALLY!!! Considering the millions of Mopars built "with ballast resistors" and the "not so" hundreds of MSD, it just might be that percentages, Mopar is ahead!!
