Is that a creek in front of #1?
#7 definitely a different hole.
#10 is a curious change, moving the green away from the lake.
#15 and #16 are obviously an attempt to infuse more drama into the back nine... I guess that's a good thing. I always thought the stretch of 14-17 was rather mundane before.
I like that 3, 4, 8, 12, 13, and 18 all basically unchanged.
I suppose some will opine that there's too much water here.... maybe there is, but I always thought for a course that called itself "Blue Monster", there really wasn't that much water in play. Obviously there will be more after this.
