Thanks Sean - an illuminating and interesting tour, as always. Indeed, a model of its kind!
Just to gloss my observation re Fowler: I noted that others (Mark R I think?) had made this point that his courses all looked different. My only point was that I saw some quite strong resemblances between the bunkering at Walton Heath and Yelverton - both have what I would describe as an almost "rampart" style.
On a related point, and for this reason, I am not sure I agree with Tom that Fowlers's bunkering is bland - not at Yelverton or Walton Heath, and not at The Berkshire (though I agree, to the earlier point, that The Berkshire does not look much like the other two Fowler courses I mentioned). Having said that - and I am not really a Simpson expert - I think some of the Simpson bunkering at Morfontaine is maybe wilder than anything I have seen from Fowler.
