Think the Multiple Strike Discharge is kinda cool. I remember a display I seen (the one it was actually wired up and working) back around 1990, you could spin the distributor, and just watch all the different arcs coming off the plug ( it was pretty cool) but I don't run one, personally. I'm kind of from the less is more mindset. More reliable, less stuff to go wrong. Like one of our members says on his profile "the parts that you don't add, don't give you any problems"
