JC, No. Your use of the term harder is incorrect. Narrower does not make it harder. It just makes it one dimensional, boring and easier for the str8 ball hitter. To me, this is not the better golfer. Maybe a better scorer, but if we expand the definition of a better golfer to include other aspects, like creative, mentally tough and all the other aspects that can come deep within a person, narrower does not compute.
The card and pencil stroke play mentality is likely behind all this narrowing. I would even argue in the todays reality this mindset and the architects that perpetuated it, are responsible for the declining interest in the sport. Why? Because it is less interesting.
Andy, This separation only confirms why golf has lost it's inclusive nature as a sport for most every person.
