1. Is Muirfield the ideal links routing? Why or why not?
I'm not an expert on links golf, but I do have some experience. I would say Muirfield's routing is ideal and among the best I've ever seen for the reasons stated above.
2. Is this an achievable model in a non-links environment? What are the major obstacles? What are the better examples of its application?
Is the routing achievable on a non-links course? Sure. You need ample land in the appropriate geometric shape. Would it be as effective, from a golfing standpoint, as Muirfield's is? Not unless you have a windy site.
3. Is Muirfield’s routing vs. wind direction the driving force behind its impressive roll call of champions?
I'd say no. I'd say it is the maintenance and mix of challenges, of which the wind plays a singular role. The course is a complete test of one's game. So, you have to be a complete golfer to do well there over the course of an entire tournament. Also, the rough and bunkers are penal. So you have to be able to control your ball and pick and choose when to challenge the course with the appropriate type of shot. Again, this is the hallmark of great players. Hence, the list of champions crowned at Muirfield.
But again, I'm not a links, or Muirfield, expert. Just adding 2 cents in hopes of furthering the conversation.
