Me and my partner driver have been the drivers since 2011. We picked because we both worked great together, and we are better at driving then anybody else on our team. Proof: we weren't there at GTR West in 2011 on practice day, the other drivers hung one tube in 3 matches. when we got there after our exam we hung 6 tubes per match for 3 straight matches. Practiceing with 610 was also pretty fun
Pick two people who know how to work together. Don't slap to randoms together. they need to understand how everything works on the robot, and the strengths and weaknesses of it also. Use the robot to its best ability, not for a purpose it was not built to do. better drivers will make a crappy robot look good. and crappy drivers wil make a good robot look crappy.
