Marc - you are right, they have been removing trees, and there are obviously more to come since I could see some of them marked with the cross of fate! Apparently they even managed to get some sort of government grant to help defray the costs. A nice wheeze!
Not sure I agree with the Sunningdale Old likeness. That is clearly a heathland course, with quite a lot of heather, and Coombe Hill is pretty much free of heather. I think you are more conscious of the trees at Coombe Hill, and the big elevation changes give it a very different feel to Sunningdale Old where the elevation changes at 4,5,10 are less in play than at Coombe Hill.
Wentworth West is more similar but still different - has a bigger feel to it, further from London, less dramatic elevation.
