Slag,
Kahuku's a thrill. Pure golf in a lavalava and bare feet.
Plantation is probably #1 but my favorite's are Mauna Kea for it's classic architecture, Wailua Municipal on Kauai for the way it's back nine(fmly front 9) uses the land despite that ugly fenced in reservoir on 17, Kiele, which by the way is going to redo 14 and 15 to take advantage of the topography and views on 14 and 15 of Nawiliwili Harbor. Prince is a beautiful stretch of property, but is target golf at it's core.
Best golf (by island):
Plantation-Maui
Mauna Kea-Big Island
Palmer-Turtle Bay-Oahu
Kiele/Prince-Kauai
Kaluakoi-Molokai
Challenge-Lanai
Best values:
Wailua on Kauai
Pali GC on Oahu (poor man's Ko'olau)
West Loch on Oahu (terrible conditioning but very interesting holes-Robin Nelson)
Dunes at Maui Lani (follow the smoke to find Willie Nelson on the course)
Kaluakoi on Molokai.
Worst Values:
Hualalai
Poipu Bay
