Mecanum vs. Tank Drive?

[Electronica1]

As much of a fan as I am of using mecanum and not picking tank without proper game analysis, if you use pure mecanum this year you will have a bad time. From what I understand, you are not protected while placing gears, so all the fine adjustment in the world isn't going to help when you are being clobbered whenever you get close. If you can't do swerve, octocanum, nonadrive or butterfly drive, then you should stick with skid steer and focus on compensating for the less maneuverability.
