I like heads up racing and did it back in the day, so to speak. But they came up with bracket racing so everybody could have a chance to win. I really don't see a track going back to that kind of racing. Don't get me wrong I think drag racers are wanting to do something different. I stopped running Pro and Super pro because I got bored with it. Plus the delay boxes. Well that's another story for sure. I say go to a pro tree for every class and come up with a way to run heads up.
It'll be tough to keep it fair though.
