Don't know whether it's possible to revive this month-old thread, but if it is, which course did you try, Reef, and what did you think? I'm facing a similar dilemma - time for just one round at either Blackwolf Run (Original), Whistling Straits or Erin Hills - on a trip to WI next month.
And, yes, I'm also planning to play the Links course at Lawsonia, a track I'd probably have never heard of were it not for GCA.
