I played it about 3 weeks ago.
I agree with Miller that winning score will be between 12 and 18 under.
The two nines are very different. The front is more hilly and the back nine is dead flat.
They have grown the rough to toughen it up but to the pros it probably won't make a difference.
The new bright white bunkers are deep and in certain cases steep. The sand is soft.
Most of the par 5's are reachable and many of the par 4's you (and certainly the pros) have a short iron into the greens.
Troon now manages the property.
The course is in decent shape, they do have a slight kikuya problem.
It's a 4 or 5 on a 10 point scale.
