It's actually a 4 wheeld mechanum so I can't address the two traction wheeled in the back but the front are the wheels in question.
Perhaps you mean the loss of torque from the configuration itself, and that's absolutely right, but that's the nature of mechanums.
I still think swapping them will solve the rotational problem and still allow forward, backwards and strafe.

Again, my mecanum knowledge is limited. I believe Alan is referring to the robot's difficulty in rotating itself with the O configuration due to the way the vector math works. However, you can likely see just by looking at the wheels in this configuration that it is quite easy to rotate it with an outside force (i.e another robot spinning you).
