Tom,
You have always said it is hard to pick favorites in deference to your clients feelings, so I presume that list would be in your last will and testament so you didn't deal with the fallout, no? And, wouldn't be hard not to pick your last two courses and your next one as your best?
Many such instructions cause a lot of grief, and I truly would hate to saddle what would be complete strangers with my wishes from the grave. If reincarnation exists, I hope to come back as a goat mowing one of my fairways....if I don't like what's going on, I can just buck em! If I am buried on one of my courses six feet deep, I may leave instructions to only aerify to five feet...
Its important to document your designs with extensive ground level and aerial photography, perhaps contour maps of the as builts, and then perhaps write a few words about how much caffeine intake was during the design process and other randome thoughts to help others learn if they wish.
Then you have to trust that your courses will be in thoughtful and reasonable hands, or that your grandkids or fans will take up for you. If not, in the big picture of life, golf course design ain't that damn important. I am not sure what happens in the afterlife, but I have a feeling I won't give a damn.
