Jeff,
I dont think it is too general. In fact I was going to list 16 at PGA West, but had to run out the door without giving any examples.
Query whether 17 at Sawgrass/PGA should also make the list. Personally I am not a fan of island greens, but I know many are. Plus these holes were/are certainly a sign of their times.
Tom, As for fitting the holes to the land, I dont mean to follow the NGLA model so specifically. First, I definitely consider the Biarritz one of MacDonald's concept holes whether it was built or not at NGLA. Second, this is a hypothetical so I am not sure we need to worry about fitting with any particular land. But if it helps you form an answer, imagine a Shadow Creek/Lido situation where you can spend a bunch of money to shape the land the way you want it.
And come on Tom, quit holding out on us. That is three times now you've mentioned this bevy of modern holes worthy of copies without naming names or describing holes.
Ed.
Welcome back. I almost excluded the neo-classic courses in my original post, but decided to let the posters decide what qualifies as a modern course. (In other words, should a neo-classic course which emulates courses of the twenties truly be considered modern?)
But we will see what people think. Meanwhile, do you have any that arent by the supposed "favored architects?" And if you are focusing on such, I think you inadvertantly forgot RC 6 and 12, at least.
