^So this is just for the sake of argument, that if you cherry pick the exact weight, speed, torque curve, grade and scenery out the passenger window, you can find a spot where taller gears are slightly more efficient than lower gears?
What happens the rest of the time when the scenery changes?
The only variable involved is speed. For each speed you pick, one rear axle ratio or the other will have an advantage given the same transmission ratios. Pick the one that has the advantage at the speed you travel most often.
Low geared rear axles are great, until you are rev’ed out and can’t pull the next gear.
