Without sounding obvious
my two picks would be TOC>> still for me the most thrilling tee shot in golf... especially when your name is announced... I was fortunate to have this in the links trophy.. and my 2nd pick would be Doonbeg... another elevated tee (if someone has a picture I would appreciate it) Interesting the New breed and the Old lady clashing....
Saunton West has the most difficult first tee shot when the wind is hurricane left to right with OB all down it and the range sheds saying ""hit me"", ""hit me!!"" Watch out for the double cross and the THICK rough on tuther side!! but then again, this happens frequently at classics like Prestwick with the railway and even Troon to a certain extent with the sea. Royal Cinque Ports although wide sets up a thrilling encounter with the clubhouse if sliced
....
Machrinhanish has to be up there though for pure excitement and getting your attention from the get go!
