Mark,
Just for fun, since you are talking the best of best, why don't you try the exercise of removing 5 from that list? Then, maybe removing another 5? Your list is great as the best, but needs to be narrower, IMHO, to be the best of the best, no?
For me, the first five would be Portrush (even though I wore my sweater from there a lot the last few cold days...nothing warms like real wool), Merion (sorry, rough to long to be enjoyable, and a few bad holes, i.e. 10), and/or Oakmont/Winged Foot/Southern Hills/Oakland Hills/Olympic for being too difficult without loads of charm), Medinah (even if my first great course played at age 15.....), Inverness/Plainfield/Aronomink/Cal Club/Cherry Hills/Oak Hills/Balusrol/Scioto as very good, but also very similar to so many just below the top level clubs, even in their local area)
That gets my list down to about 30, and it gets harder to cut from there, as all 45 are excellent courses. And, just as being outside the top 100 shouldn't really offend a membership, being outside my personal top 30 shouldn't either, and certainly no offense implied.
