Drive system to be used?

id like to hear your opinion on what drive system should be used in this years robot, we were nearly positive on tank but due to our inclination for mobility we are open to ideas

Given our success last year and the simplicity and robustness of the design, my vote would be for Tank-Drive. Swerve would have a mobility advantage over tank but I do not believe that the extra design time and weight are worth the change.
