On my trip I played CS, Nairn, Dornoch, Kingsbarns, Gleneagles King's, and The Old Course.
By "americanized" I mean more user friendly. Guinness draft vs Guinness stout.
At Nairn, for example, the fairways are more narrow. More penal for a miss into the love grass.
Whether it was CS being new, and not mature in the "rough", I felt it was more forgiving. Less penal. More senic.
Get the tourists like me to come back.
Don't get me wrong, I enjoyed it greatly.
