We have initial "tryouts" for driver, operator, and human player before the regionals. Then, at our first regional we rotate the people who were the best in the tryouts. This allows us to find out how they do under pressure, and gives us additional opportunity to evaluate performance. This year we rotated two drivers, three operators, and three human players. Before the elimination rounds at our first regional (Cleveland this year), we make the difficult decision of picking the "best" operators so we can, hopefully, perform as well as possible for our alliance partners.

Once we settle on "primary" drivers and human player, we stay with those people unless there is a very good reason to change.
