Well, with the price of tile doubling in the last year and a half, the difference will be .20 +- per foot. I would not call that pennies.
Some thoughts from an old guy;
Years ago, 5" was the gold standard, why. Because the grade control ( Targets and a "gun sight") with a person working the hydraulic lever, gave you a + or - range of one and a half to two inch grade. So, several years down the road, you actually had very little flow space, probably the than a three inch line put in with the current GPS control system on the OP's plow.
