I've seen this sentiment a few times and while I agree, I wonder how much of this is actually caused by the design or simply just lack of familiarity with the course since it's new to the tour. As this course is used in the future, will we see more uniformity of approaches on the holes as the players learn the course better? I think to a large degree the answer is yes. It seemed like a lot of players were already emulating each other's strategies of going very wide off many fairways because there was no punishment for doing so and the approach was just as fruitful.
I think a few more mandos will be added. Obviously the triple mando on hole 18 that wasn't listed in the caddy book will be in next time, but it wouldn't surprise me to see a few more.
