This guy has a guest column in DRO about this. He has determined that he enjoys 1/8 better than 1/4 mile. I've never seen one in person, but on TV it looks over before it starts! When they show those 1/8 Pro Mod races on IDR, it's like Green---1st gear---shift---parachute! Maybe it's a Southeast thing but it doesn't do anything for me!
