Everyone uses MSD 6AL. One per coil if running through a distributor or 3 if running direct fire. I MAY possibly run both. I have a GSLSE and am going to switch over to the FC leading coil and keep the trailing stock running through the dizzy. Only because there's no real cheap way to convert to the FC trailing coils.

Anyways, I am looking at the MSD DIS-2. (2 channel vs the 6AL which has 1 channel meaning you could run 2 coils) I was told that the DIS-2 will not work for rotories. Is this true? Has anyone had any experience with it?
