I switched to the Little 5 from Nite B4 in '03. Got tired of the support junk and the goofing around half the night to get to the midget feature.
Little 5 is 2 1/2 hours of the exciting semi-controlled mayhem that sprintcars put on. And it's sprints only and you don't have to put up with Bandeleros, etc. Not that there's anything wrong with it.
