Sean,
When it comes to ratings, it depends on whether you rank the composite course or the east and west seperately. The composite course is defintely a better course than the west course.
The composite course was regularly rated in the world's top 6-7 courses but the recent trend to rate the two courses seprately, Ernie Els's 60 and and some pretty average course conditioning has seen the course slip. As Bill says, its a great course but so is everything else in t he world's top 10.
