Of the seven I've played, Winged Foot, comfortably.
How would you compare it to Spyglass(since you played the state champ there) and Olympic(if you have played it)?
Lake Course might be tougher tee to green because WFW is fairly flat, but WFW seems harder around the greens. Getting up-and-down at WFW just felt impossible—every time was a 7-foot-deep bunker to a green that slopes away, and then goes over a hump, and so on.
Spy played very tough during the US Am with firm greens and 4-inch rough. But if the weather is good, the fact that it's under 7,000 yards keeps it from being really crazy. At WFW, a pro who drives it 300 would have 6 approaches under 150 yards. At the Lake course they'd have maybe 8 depending on choices off the tee. At Spy they'd have 11 or 12. If Spy added some new back tees and made it 7,200 or 7,300 yards, it would be just as hard as those other two.
