Hey guys most tracks go by roar rules. When something comes up that you dont think is right go to the track owner and ask. Alright on the topic of pro or sportsman. Buggy and truggy are the two classes that have sportsman or pro. To be completely fair it should be like all the other classes. Everyone in buggy runs together. After the first heat split the next heat up by their times that way everyone runs with people close to their lap times,that is the reason for A B and C mains. A few years back track owners used to give a small prize for the first three places in each main. That way everyone runs close to the people closest to them and people were proud to run in each of there mains.
