Ian, this should be the most active topic on GCA.com! It is the essence of what the controversies have been about regarding new course development and restoration-remodelling.
Will there be some sort of golf association analysis of the results of this experiment, published? It seems that this is the best sort of test case we can hope for. Yet, it is one lower tier competition, in one isolated setting. Did they keep GIRs and driving distance and accuracy stats in this competition and compare them to the participants normal stats? What distance yardage was the event played from?
I sincerely wish the ANGC committee would take this example to heart, and finally give this sort of unique competition ball requirement of a one ball spec for all competitors a reasonable try, at least for one year. They could put tee boxes back up a bit, and just see how this all plays out.
