40 compensated for that low traction-ness of their wheels with a traction plate. However, they tried to push and get up the ramp where traction is half of the battle.
I'm not saying they are a bad idea all together. Last year they were a great idea. This year, where defense is much more important than previous years, mecanum/holonomic drives aren't the best way to go.

I would have to disagree with you. Our robot this year has mecanum wheels and we played defense just as well as anyone. We were pushing 6 wheels and 4 wheels.
The rollers on the mecanum drive system are not made of plastic; they are made of urethane. Urethane is more like rubber in that it provides traction. It also allowed us to get onto the ramp. I believe that our choice in drive train was a very good one. I don't believe that any drive trains out there are any better than the others, but it just comes down to how you play the game. If you would like more information on our drive train, you may find the info you're looking for here:
