Was recently out at Sebonack and thought the greens, like the rest of the course, were a true collaboration. Tom's contours are still a bit more than Nicklaus is used to, the greens are a little smaller than I expected, but they vary from 4,000 sq. ft (5th) to 8,300 sq. ft. (3rd hole). There's nothing small about the site, by the way, though there are some wonderful, intimate green settings (1st, 2nd, 5th, 12th, 17th).
