Option A, all the way. In the B scenario, the robot would only be useful for the bridge, which, while useful, isn't enough for one robot.

Though this is a hypothetical situation, in the real competition a wide robot that can score 80% of the time, feed really well, actuate the bridge, and works well when doing a triple balance would be the one to pick. My reason for saying this is when it comes down to it, you'll need a robot that can score in autonomous accurately, and in teleop if needed. Balancing the bridge IS easier for the smaller robot, however as proven multiple times over the weeks, it is possible with 3 wide robots.
