Team 231 chose us as alliance partners in the finals. I'm not sure, but I believe they had omni wheels that were all at 45 degree angles.
Yes, they did get pushed around; however, their driver did manage to "roll" around defending robots and pop a couple in the goal. Another advantage they had was, their infeed rollers were mounted on the long side of their robot, and their shooter was too. This provided room for the shooter and a large margin of error for the driver when they needed to pick up balls.
Here's the second match in the Lone Star Regional finals, if you really watch it you can see that nifty roll move used a couple of times.
