Fortunately we got 1662 on our alliance, and they were the only team that I saw push 753 around. 1662 had 4 2" wide, 8" diameter IFI traction wheels, and they could push around whoever they wanted. Their robot was a little on the skinny and long side, though, so they hopped quite a bit while turning.

I felt that 753 had too much traction and paid for it in the finals when they started tripping breakers from drawing so much current from its drivetrain. Besides that I that that robot was great and I look forward to see it at nationals.
Our robot this year uses 6 wheels that only has 4 on the gound at a time, which allows smooth turning without sacrificing any traction. I felt our robot could push almost everyone at Sac and SVR, but 1662 proved us wrong. our robot has a wedge on the back and 1662 rode on it, putting them on two wheels and they still pushed us. I felt that 1662 had the most pushing power and traction but suffered from an inability to turn smoothly.
