Tom D:
I agree with you in terms of the interplay of a land's natural features. They should clearly be brought into the equation.
Allow me to go a bit beyond that -- I see superior routings as one that maximize all the internal elements that a particular site can offer -- e.g., wind direction is calculated into the mixture so that a course doesn't play simply "easy" or "hard" because a certain wind direction is blowing. In addition, you have a golf aspect that creates a myriad of different shots throughout the round.
Peter:
I agree with your take. Candidly, too many courses don't provide beyond an average design level in terms of their overall uniqueness / complexity. Golf is a game of shots and holes. The best courses are the ones that call upon the widest dexterity of skills for shots to be made in an 18-hole round. In addition, it behooves a quality design to have 18 holes that provide for a complete test in which repetitive situations are kept to a minimum.
A superior routing does what Doak mentioned -- it encompassses all the natural features of a given site and at the same time, I believe, it also doesn't allow for a sameness that detracts from the time spent there.
Given this understanding of your meaning of routing, I'm not sure I'd agree that VV is the best of the three. Even around diversity and routing there are pros and cons to each, with no clear winner IMHO. To compare just the two VV and WKPS, following is my assessment.
The VV property is more gently sloping, while parts of WKPS are more abruptly up and down, even within a hole (six for instance). C&C have used the ups and downs within holes very nicely I think. Kavanaugh had less opportunity on his property to show that skill.
In terms of the directions of the routing hole to hole and the impact of wind on that, I think the two are pretty much of a wash. VV is a large counter-clockwise loop on the front, and then out and back (with 3 holes at right angles to the out and back) on the back nine. At WKPS the general layout is out and back on both the front and back nines, but there is a 90 or 180* change in direction from hole to hole on the majority of the course. It was fairly windy when I played both courses and I did notice the wind direction was changing from hole to hole. I doubt that either course would be more susceptible to one wind direction or another.
As for variety of shots, testing the whole bag and your skills, that's a tough one.
VV no doubt presented more recovery options around the greens than did WKPS. Lots of closely mown run-offs.
There wasn't much to choose between the courses in the mix of holes in the routing. My only complaint would be that C&C put two long 4's back to back at 12 and 13.
VV had two longish and two shortish par 3's. The last one was dull. WKPS had two shortish par 3's on the front and 2 longish ones on the back side. The first one was kind of dullish. I don't see a huge difference in shot values on the par 3's between the two courses.
VV had 2 very long par 5's (600 yds) and two medium length. WKPS had one very long par and one short par 5 on the front along with one medium par 5 on the back. Given that I have to play most par 5's as three shoters there isn't much to pick between the variety of shots on the medium or very long par 5's. WKPS gets a small step up by offering one short par 5 that I could reach - the 8th.
On the par 4's WKPS had four long to very long ones. VV only three. VV had two shortish par 4's and one was reachable for me. WKPS had 4 shortish par 4's but none of them was reachable and all encouraged me to hit iron off the tee. That got a little repetitive. One up for VV for me.
VV had many more holes with centreline bunkers - that got a little repetitive. WKPS had some, but fewer.than VV.
WKPS had a few blind tee shots and one fortress green. An advantage if you like those features and shot requirements.
VV frequently had a fairway bunkering approach that placed bunkers on one side of the fairway at a distance that I could safely drive up to. On the other side of the fairway was a bunker at a distance that I probably could carry and achieve a better line to the green. Good concept, but perhaps a little too reptitively done.
WKPS had more varied uphill, downhill and sidehill lies in the fairways.
So all in all, pros and cons each way. I can't pick a clear winner on diversity or routing in your definition. You can. Peace be with you.
