I see Bandon as good for the game. It makes a splash. They are the right courses for the right place.
I understand the point that for everyday play, they may fit into the "hard golf" theory that many say is driving people away from the game. If courses of the Bandon level difficulty were typical of everday courses (and in some cases, we all believe the CCFAD model has too many of those) in every locale in America, the difficulty of the design would probably impede golf's growth. But, you go to golf resorts to get something you don't see every day on your typical rotation of courses, no?
It's not a question of good or bad, its a question of perhaps the market being saturated with high end resorts. But, its dog eat dog and Bandon has simply and rightfully diminished some other courses reps and biz.
