My question is: What mechanical advantage or modification is necessary to make the mechanum wheels strafe?

So a 2:3 reduction off of a CIMple box is a 7:1 total reduction, which is not enough. With 6 inch wheels, you need somewhere between a 10:1 and 12:1 reduction to have enough torque to strafe. You can get this with either a larger reduction coming off the CIMple box, or replace the CIMple box with a toughbox.
