Matt, the pHairway is 10 times more acidic than the vinegar which leaves the vinegar more expensive by my quick calculation. I have never heard of anyone injecting vinegar in irrigation after 400 clients in 26 countries.
I would suggest buying 46 to 49% sulfuric acid and adding in urea when the all sectors of the course need nitrogen.
If you have multiple injection units than you can better accomodate nitrogen input to greens, tees, and rough /fairway areas.
In any case with generic sulfuric plus urea you save a pile of money. Whatever the pHairway vendors may tell you about monoproteic reactions, the head engineer of Agrium told me pHairway is generic sulfuric acid plus urea.

ps vinegar made some darn good sushi from striped bass in Long Gisland though
