Ran I would concure with every course on your list. The problem is limiting it to just ten. Certainly courses that reflect Colt's genius (Muirfield,S.Forest or Portrush),Tillinghast's park-land strategies(Winged Foot,SF or Somerset Hills),Flynn's flexibilty (Cascades, Shinnecock and Huntingdon V.)or Thompson's malt induced artistry (Jasper,Banff or Cape Breton)would also be worthy of study.When analysing the influences of the great golf architects and their works, you find one common thread, The Old Course. MacK.,Colt,MacD.,Tillinghast,Fowler,Simpson, Park,H.Wilson,Alison,Ross and Park were profoundly influenced by St.Andrews. Ross, Raynor,Flynn, Maxwell,Thomas and Thompson were at the least indirectly influenced by the Old Course. I think it can be argued that StA.is not only the cradle of golf, but also the cradle of great golf architecture.
