I'm with John Kavanaugh on this one. He and I have discussed this before, not in such specific terms.
Let's draw the line at 1980. Me and John get to play everything built after 1980 for the rest of our lives, versus the classics. That means JK and I get everything by Fazio, Nicklaus, Doak, the Jones brothers, and Coore/Crenshaw, including those they haven't even built yet. Plus we get most of Pete Dye's courses. And that's only the famous guys.
