Many thanks for your replies. The list was intended for serious criticism - I'll wait a while longer for a few more opinions before trying to refine it.
Scotland:
How could I have forgotten about Loch Lomond!
Again, I'd forgotten about the St Andrews Bay courses.
Southern Gailes is too new for me to know anything about it (though I'll try to look in when I'm a Troon at the end of the month).
I didn't think much of the Roxburghe, but I'm happy to see it there if someone can make a plausible case for it.
Ireland:
I'd happily put in Portsalon and Enniscrone.
Don't know anything about St Patrick's (and it's his day, too).
St Margaret's can't be too remote - it's close to Dublin Airport.
Do you mean Adare Manor or the Adare Manor Hotel? As I understand it, Adare Manor is the 1900 course of Ben Sayers and (later) Eddie Hackett but is usually confused with the RTJ course at the Adare Manor Hotel. I have a feeling they even got into a legal wrangle when the hotel tried to pinch the club's name. RTJ described his 18th as 'the finest finishing hole in world golf.'
With two Carton Courses, another at Powerscourt plus other Irish courses such as Headfort, many new courses by Christie O'Connor, Des Smyth and Philip Walton, would someone who knows Ireland better than I like to try to assemble the Irish courses into a league table?
? Dangerous territory!
England:
I don't know anything about Queenwood yet - they refused to give me any information when I tried to contact them for the Times Guide.
I'd go along with the Duchess at Woburn.
I found Moor Allerton bland (though I'd completely forgotten about it when compiling the list). I toyed with putting in Stockley Park near London (another RTJ course) which I rate quite highly - it makes you think on every shot and is a wonderful resource in the midst of a large factory estate.
I'm not a great fan of the Edinburgh at Wentworth - I found it very uneven, some fine holes and some real makeshift stuff. I know they had an awful lot of restrictions when they built it (a friend of mine was a consultant environmentalist on it). Again, prove me wrong and I'd happily knock out something else.
Keep up the criticism - I am already hopeful of a much more fulfilling list.
