Troon North Pinnacle shouldn't make the list IMO...something tells me I'd say the same thing about Monument as well.
Most of the courses at the top of the list are pretty standard and should be there. The biggest weakness I see is that this list seems to include all the BIG money places that from comments may or may not really be great courses. I haven't played quite a few of those though, so I could be totally wrong about their merits. In addition to Troon North, do Grayhawk, Trump National, Doral, Wynn, and the like merit inclusion?
Also, IMO the Engh courses are too low. Lakota Canyon, Redlands, and Tullymore should easily be in the top fifty.
It seems to be with all the good public courses in Indiana that something should be included. That said, none of my favorites in that state even make the top five on the state list, and as usual Sultan's Run isn't included at all. I'd play it, Rock Hollow, Warren, The Fort, and French Lick before Troon North any day.
