John,
I noticed that there has not been a lot of response to your question. I saw the course from far away while playing at Kukio on the Big Island this past summer. Not a lot of play on the course. It sits on the slopes/foothills of one the volcanoes, quite a distance from the ocean. One of the assistant pro's at Kukio that I played with had just won a tournament at Nanea. Sounds like they have a good relationship with the local .PGA Section for a fair amount of tournament play. From a design standpoint, however, I can't tell you very much.
