Matt,
There were a lot of small changes that I have tried to call out in the photo review.
From memory they are as follows:
#2 - The rough that split the fairway left and right has been toned down a lot - you can still see the dividing line from the tee, but it is not as gnarly or penal as originally designed
#5 - The bunker that was tight to the green has been removed - so there is a fore bunker still, then about 30 yards of open area and then the wide but shallow green
#6 - The rough, long grass, etc. that split the fairways has been toned down so it is easier to see what is out there - left side versus right - and a drive that is right up the middle will not be lost in the long grass, etc.
#7 - The right side of the front bunker has been chopped off and several mounds have been removed. This has created a "bail out" area for short hitters.
#8 - Two mounds in the fairway and one that was just right of the tree, have been removed. Short hitters no longer have to worry about knocking a drive into the mounds. For everyone else, there is not change, but I really liked how those mounds added confusion to the tee shot.
#12 - The mounds in the fairway have all been removed so there is a waste area left and long, and trees to the right, but the fairway is wide open.
#13 - The mounds in the "lay up" area - center of fairway and left of fairway - have all been removed which makes choosing a lay up distance much easier. I kind of wish they had left one of the mounds on the left side because they were pretty much out of play but add character to the hole.
#15 - Some long grass has been removed in front of the fairway bunker (which is located on the right side of the fairway) - so, from the back tees there is room to hit a good driver or 3 wood amd end up short of the bunker with a great line into the green.
#16 - This hole has been altered more significantly than any other and I think they may have gone too far (the Head Pro also thought that a bunker should still be in the fairway). At this point, all of the mounds in the fairway have been removed, there were a couple short of the tee that some short hitters were losing balls in, and then they also took out the bunker and the surrounding mound that protected the speed slot. They are also growing out the rough behind the green which will prevent balls from rolling off the back, over the cart path and into the nasty gunk.
Overall, I think that most of the changes were okay. I thought the course was fine in its original state but I also understand that losing a ball in the middle of the fairway is really frustrating. The grass on the remaining mounds has been shaved down so the "mohawks" or "eyebrows" are no longer there.
Essentially the course has been "tweaked" - the routing and bones of the course have not been altered.
The one thing that bums me out a bit is that the a lot of these mounds added uncertainty and confusion which really make the golfer think. The mounds often functioned like fore bunkers, making it difficult to feel the distances between tees, fairway, greens, ideal landing areas, etc. Most people would probably not embrace this aspect of the design but I liked it.
