Welcome to RCU, deciding as to a straight run or a course setup with right and left turns will be for the club to decide. Usually you can have more broken parts from a road course than straight line driving. Straight line style will depend on who has the most dollars usually while making right and left turns will depend on the driver as well as the vehicle.

Thanks you for the job you do and good luck with the club.
