In England, Ealing Golf Club seem to be the best - certainly they get the most publicity. Lots have been waiting for the HGK to come unstuck, but he hasn't yet.
Beat me to it Ryan. HGK there has a good concept that he follows. It produces good putting surfaces even through the winter. I played there a few years ago now in mid January and the course was on full greens which putted really well. It certainly is not my philosophy but hats off to him it certainly works.
Brett,
all greens in the UK have some poa in them but those courses you mention would have less than 50% stand of poa and so not considered a poa green by myself.

I think Ealing have a healthy budget to allow him to weave his magic, I think he puts down something like 300 tonne of dressing every year, cuts at 2mm, new blades, constant grinding etc. Can't knock him though, it works for him and he's elevated the status of Ealing (and himself) massively.
He says that it is sustainable - meadow grass is indigenous and to be fair all but probably 5 star places like Grove, Wisley and Queenwood, everyone who has ever fought poa in this country, inland, generally loses.
