Sooo, as the only person who can truthfully say they have played EVERY course that has EVER been included on any reputable World USA top 100...I would offer the following comments on courses questioned above:
Santapazienza--played 4/23/2023. First put on a World Top 100 by Top100website (I am a Golf Magazine Panelist) in 2020 and subsequentially underwent a major renovation which was completed about a year ago. Based on my 2 day visit (day one arrived late and just did a drive around the course with one of owners...played it next day), it did NOT belong on a World 100 list in 2020 and Tom's comment is correct...but IMO today's course is deserving to World 100 status. It is very big and bold from Blue and Black tees boxes...and yet playable and fun from white and front tee boxes. It's one major negative os long distances from green to next tee on front nine which is located in a rain forest. Environmental laws make it illegal to cut most vegetation in rain forests...and the drives on the cart paths thru the rain forests (Note...these paths were cut before the environmental laws were enacted) are literally fascinating.
I TOTALLY agree w Tom regarding Ardfin, Alotian, Canyata, Pikewood Natl, Rich Harvest Farms, and Nine Bridges. Disagree regarding Congaree and Whispering Pines. But as I have said before...there is no "right answer" to this stuff...it is like picking a spouse...everyone had different tastes
