Not sure if this will end up being significant or not, but since it has not been mentioned yet, last years horses coming from SA were going cushion to dirt and this year it is an entirely different synthetic surface. Maybe it makes a didfference, maybe not. This, in addition to the running styles of Col. John and POTN, makes it dangerous IMO to compare POTN to Col. John, but this isn\'t to say the same result may not be possible.
