My favourites are in order:
St.Andrews
Bethpage
Kiawah
Congressional
Oakmont
Merion
Olympic
Royal St. George
And i would wish we had
Hilversumsche to go a full stroke on!
Well i use to say i hate em all, its the truth, on black tee there is no easy courses, i play them all, but not with excellent results every time ;-)
IMO should the hardest/famous and par 3's not be here at all, hardest aint the hardest holes, none from oly/oak or merion and famous i've renamed to best of bad glitches, its the course where you have the best opportunity to loose a ball in water, cause wind dont tell the truth and meter goes crap!
