FBO or MSD what do you use?

I'm running FBO on the 72' and have been happy so far. Although the car doesn't see very much street time, so the verdict's not out yet. It has revved up to 6000 RPMs with no problems.

I'm running the standard Mopar electronic ignition on the 73 and have not run into any problems there either. Neither of these cars see much street time.
