Garland,
I think it would change with the nature of the projects HF manage to get before the next writing. When Jack Kidwell ran the firm, they focused on the low priced public model. Somewhere they morphed, enough for some one to ask Mike to write a book. The 2005 list is probably a result of their continued morphing and having gotten the Erin Hills contract, which in his personal experience elevated the % of owners who demand tournament type courses.
In the market, there is only so much room for upper end, distant resort or getaway golf experiences. It is not even certain that the Prairie Club is going to be a financial success this early. The owners will only build what works for a market segment, and that is only a small part of it. For CC, Doak, etc. they may very well still be having owners asking them to give them minimalist resort courses. My requests might still be the same for fun publics. HF has a broader portfolio type than most gca's, which should be considered in assessing their list in addition to timing of the list.
