Mike:
I don't think all of your queries were answered...let me give those a try. First I think its difficult to assess the course by just watching Toms and Mickelson play...WWPB was not constructed as a major test for the pros. There are much more strategical considerations for us mere mortals.
The double green had trees between the two greens.
The two greens on #12 couldn't be any more different. Last I heard the relatively boring left green is abandoned. The right green is semi-blind up the hill over a sand pit, with the wildest contours on the course. The other green site is practically bunkerless and much more mild. They in fact make the hole play completely differently - as I understand at PV that is not the intent.
It seemed that WW had only one dogleg-#18.Is this true?
18 is the only severly doglegged hole - probably 45 degrees. But many of the holes move one way or the other:
2 dogs left
4 is only straight for the long hitter - others will treat it like a dogleg hole
6 similar to 4 - the landing area for the 2nd shot is well left of the line to the green
8 & 9 move about 20 degree right.
12 moves right to the right green - a tee shot can be blocked out if played too far right.
14 ranges from a slight dogleg left to a larger dogleg depending on the player's strategy
15 only players going for the green will treat it as a straight hole - for mere mortals its either a dogleg right or left
18 previously mentioned.
Is the width between the trees anywhere near the same?
Hard to answer this one because there are many holes not outlined by trees, which I don't believe is true at PV. The PV-type holes aren't really surrounded by the pine trees. The holes surrounded by the trees vary slightly in width, while the ones not outlined by trees vary widely in width.
Aren't the waste areas mostly parallel to the line of play? PVGC's create angles that need to be carried.
There are many waste areas that need to be carried, while other carries are optional.
4 is optional off the tee, (nearly) mandatory into the green
8 mandatory carry into the green, but bailout to the left
12 mandatory carry to the right green
14 (nearly) mandatory carry for 2nd shot
15 optional carry off tee to get better angle into the green
Some of the bunkers/waste areas are deep, but there are tame ones as well.
Now about the routing of WWPB...
