I can't explain how rankers think on these issues, but I would suggest that RME will suffer a drop in the rankings over the next few years.
I imagine that lowering RM in the rankings may have been a 'no go zone' in the past, but maybe the changes to a significant number of holes will trigger a bit of a re-assessment and it's ranking may suffer slightly.
I agree with Brian that there are some fantastic holes, and great architecture on some of the 'outer paddocks'. Comparisons with the composite holes are inevitable and they will always suffer because of that.
The changes to 6,7,8 & 15 were all done in the name of 'boundary issues', I'm not sure they ever suggested they were improving the course did they Brian? Clearly, they haven't.
With the boundary issues resolved (hopefully)on the outer paddocks, it would be a mistake to make any more changes out there I agree.
