I find it hard to think anything other than the fact that Peter's firm is awarded a considerable percentage of tenders based on his Open Championship record, and not the calibre of his design portfolio.
I think the posts of Andrew Summerell, Dave Elvins & Mark Ferguson are pretty much spot on. They are informed, intelligent and considered opinions, from men well versed in quality golf design.
Personally speaking, I find the work from Peter's firm (in its various forms of acronym through the decades) largely overly penal, uninspiring, and possessing a distinct sameness, irrespective of site. Their Australian courses are in north Queensland, Gold Coast, New South Wales coast, adjacent to the Murray, and the Mornington Peninsula, among other sites. Many are given the same treatment.
I think National (Ocean) is a site of rare quality in a global sense, and the results given the budget and possibilities, are quite disappointing. The routing is quite unimaginative to say the least.
The recently published Golf Australia magazine ratings has Moonah Links (Legends) at 23 , National (Ocean) at 31, Moonah Links (Open) at 39, and Hope Island at 48. I personally feel these ratings flatter both Moonah Links courses and The Ocean. For a firm having built so many courses in this country, 4 courses in the top 50, and one in the top 30 is a result which would not satisfy me, were I the head of the firm.
I've never met Peter Thomson, but would sincerely love to do so. He's no doubt an intelligent, well-spoken, articulate thinker, with a CV in professional golf with few peers. I keep wanting to understand what he does, and wanting to give him the benefit of the doubt. I am frustrated that he designs and builds golf courses which I find so consistently disappointing. And, as been said before, the renovation work is of lesser quality. Jarring, and at stylistic odds with existing design facets. Their re-worked greens at Metropolitan (4) and Kingswood (11) are so clearly a departure from much of the fabric of the respective courses, so as to be a blight.
Neil C - I agree with Andrew, in that Mike W & Ross P may be solely responsible for some work, with Peter delegating, or busy elsewhere, but ultimately, the outcome has Peter name on it, and anyone in this position must accept some responsibility for the finished product.
