I definitely get the argument of conditioning for a regular play...I personally would rather play a well conditioned course vs a poor one every day.
My point that I'm trying to make is that it probably doesn't make sense for the top 100 to 200 courses in the world. Save a couple (Augusta for example), is their condition so good that it would influence a person to play somewhere over another? I haven't played enough really good courses to know but I'm guessing it's not.
But an example, Harbor Town vs East Lake. Their rankings are fairly close on the US scale. I'm guessing their conditioning scores were far apart. East Lake was immaculate, Harbor Town was really good, but it's still a public track. I know I'd choose Harbor Town 8 or 9 out of 10 plays.
