A lot of the G/S crowd, like me, like points because we can use the Points-in-a-Can that only came on the 79-80 airheads (? somebody correct me on this if I'm wrong, calling Datchew!) The enclosure seems to make them last a lot longer. Maybe it's just better made?
I haven't heard great things about the older exposed points systems. Seems like a lot of folks go to a Dyna 3 if they have that.
