For maximum power, I would think you would want to match the torque curves of the 775 to the CIMs for efficiency. But, in my opinion, the extra power is wasted, as you can only get so much to the floor. On the other side of the coin, if you are looking for more speed with lower amp draw to each motor to prevent the circuit breakers from tripping, then the extra power will help to do that. You will find that there is a maximum speed that you will reach regarding your drive team's ability to control the robot.
