Ed,
Having never played a heathland course, I can only speculate based upon what I have read , what that means. WN was built with more of a Pine Valley motif in mind, with playable waste areas through much of the golf course. It was clearly built as a tournament course, as much was written about trying to lure an Open here in the future. It is on a relatively flat piece of ground, with minimal elevation on just a couple of holes. Water is in play on about 5 holes (don't believe that is a feature on Heathland tracks). There are a couple of stinkers in my mind. On 10, it is OB right with a large waste area that narrows very quickly from the left. When the NCAA regionals were there, almost everyone took driver way left over the waste area into the 18th fairway, then approached from there with a short to mid iron. There is a waterfall behind 14, which is a 3 wood and a pitch over a pond. There are some good holes. 17 is a good par 5 with a 2 risk reward shots, (a cape style drive, plus a second over water) Eight is a drivable par 4 over water, where the safe play left leave a delicate pitch over a bunker.
In terms of making it better, I don't know, maybe some more interesting greens and more memorable par 3's ( I have played it 10 times and I had trouble remembering them all and I have a great memory for courses), as they are all a bit blah. One uphill, one down hill, two flattish. Overall it is just kind of uninspiring, a coourse that could be replicated anywhere. Frankly, I think a course down the street (Druid's Glen) may have a better layout...
