So yeah, in a competition (and you reaally wanted to use omnidrive), I would look into using Mecanum instead of this setup.
I challenge you to show me the math (or at least the reasoning) to why you believe Mecanum drives to be more efficient than Omni drives.

Hint: Consider both drives moving not only in "straight" directions, but also diagonals.

As for traction, Vex quotes a CoF of 1.0 for their Mecanum wheels and a CoF of 1.1 for their Omni wheels.
