Tom, the 13th at ANGC is an iconic hole. Why change it? It's terrific and fun. The changes they are proposing seem to be just to make it harder to make a 4 on the hole i.e. to protect par. That's not a new concept, but if the cost to do so $50m, is that a price to high to pay??
TV broadcasts are golf's best avenue to reach the largest potential number of golfers regularly and in a very powerful and graphic way. As amateur golf gets very little attention relative to pro golf, its the courses the pro events are played on that we see and therefore what shape the perimeters of many golfers about what a 'great' golf course is. Im not sure that is in debate here.
I designed a premium level members golf course in Newcastle, UK (Colt Course at Close House) that is currently being considered as a host venue for the 2017 British Masters. It was not conceived as a Tour venue, but the owner is now keen to see if it can host the event and so the European Tour have been challenged to try and fit the required infrastructure in. The course has about 300 foot of elevation change from its highest to lowest point (the same as Pasatiempo). Every hole goes in a different direction and slope of the previous, and with each fairway changing in width. There are a lot of elements to the design and it's been a great success with the members, with the various events held, and it is fully embraced by its ambassador Lee Westwood. At just under 7000 yards it's not a long course, but very much a shot makers course, and, based on this thread, I think a course that rewards golf played with a positive and attacking spirit. With that background, I am finding it really interesting hearing what the European Tour think of the course and what they think may need to happen to make it ok for the pros. No decisions have been made, but I wonder if what they propose may remove some of the features of the course that define its identity. This experience is making me think more about the other courses we see on the TV, and why some of our most interesting/quirky/expressive courses don't become Tour venues. It may be to their benefit that they don't.
