Simple answer - If you can only afford to reduce the rotating mass of two wheels, make them the drive wheels. Obviously, the drive wheels are the ones that would benefit the most from reduction in rotating mass, since it would essentially be a reduction of weight that the engine has to turn during acceleration, and overall weight as a bonus, for cruising. Less work for the engine == better FE overall.

I thought I said something to this effect earlier?
