I think it is too easy to only look at this from a few tournaments though. Too many classic courses no longer feature on tour, due to the distances the professionals hit the ball. Not all courses can afford, or want, a complete redesign.
True. Didn't St Pierre host a Solheim Cup? Fulford, Forest of Arden are two more I remember regularly hosting top pro events but would be taken apart these days and the cost to keep up has seen them go (along with a lack of sponsorship in golf in the U.K. But that's another thread)
