Freebeard, I like points due to simplicity and on-the-road serviceability. Most do not know, points also make a longer spark than electronics. As the fuel-air mix floats around the chamber points have a better chance to ignite the mix. MSD had to invent Multiple Spark Discharge to simulate the longer spark at lower RPM's. Even their own graph starts at 3,500 RPM because at lower revs, points do fine. Even at higher revs, points swap first place with electronics up to 6,000 RPM. The REAL reason for electronic spark is to time it with computers...NOT because it is so bad in a car motor. YES, YES, YES, electronics is better when used with Fuel Injection, computer controlled transmission shifting, working with smog devices and a computer. My 65 mustang 6-cylinder had a Pertronix sometimes and points sometimes, and I never noticed any gain/loss either way.
