Well, I guess I asked two questions... The first was the best courses from any age that are non-links or heath...
But I commented that 100 year old courses can seem to take on a natural evolution of their own through drainage, water courses, maintenance practices and topdressing that can turn a course initially on crap soil in to a firm and fast beauty... Even if we don't have anything in GB&I to compare to an Augusta or Merion.
So I wondered about the moderns - particularly parklands - that might evolve in to better courses in the future?... I'd immediately strike off the three Archerfields, Kingsbarns and Castle Stuart from that list because of seaside settings, generally good soil and a links style... I'd leave Queenwood on because although it's aiming at heathland through its planting of heather, gorse and fescues, it was built on farmland like the two courses at Foxhills next door...
My favourite modern in Ireland is probably Adare (Trent Jones) because I think the routing works perfectly beautifully by placing tees right next to previous greens - It is a surprisingly easy walk for a monster-modern. I also like Nicklaus's new course at Killeen Castle .
3.5 years later...and nothing much has changed. Modern Parkland, only
Bearwood Lakes (of that I have played) springs to mind as a contender for top 100/get better over time....but Bearwood is far from a great course so I expect there are few other good candidates out there...probably Loch Lomond or Queenwood.
Best non-links/heath? As seen above the definition varies depending who you talk to, but my take is
Gleneagles Kings...clearly not a links or heathland...awesome course...current work makes it even better...lets hope the Queen's get a treatment
Kington...see above, but not quite so awesome as GK...plus...the course has been around 90 years without being ranked...so I don't expect that to change
Ganton...I believe this to be as much links as anything, if not, heathland, so I would discount it, but if folks want to say Ganton is sue generis thats okay by me
Sacred 9...I can't in earnest call this a heathland course..and it is great...if it is never ranked its down to stupidity
...still, stupidity often carries the day
Castle Course...faux links, but thats a far cry from links...I see this course getting better and better so it may be the exact fit for what you are asking Ally...in the right hands and with enough money...I can see this course being great one day
Little Aston...always used as a classic parkie example...certainly a strong contender for top 100 GB&I...great? It would take a Dunlop White to make that happen
Southerndown...as the name implies, its a downland course and a very good one at that...certainly a strong contender for top 100 GB&I, but I doubt its ranked now...I don't see that changing
Addington...not sure what this course is...feels 100% parkie to me, others may disagree...huge potential and should be unquestionably a great course now...needs a Dunlop White
Huntercombe...to me this is a downland course filled with trees, but as with Kington...if it ain't ranked now I don't see anything much happening on this front in the future unless trees are whacked
Blackwell...classic parkie which is slowly being revamped...I see this course improving and could possibly hit the top100 some day, but I struggle to think it will ever reach greatness
Cavendish...for me this is a bottom feeder top 100, but nobody else agrees...I don't see that position changing
Knole Park...see Cavendish
