While many think golf is about all passion, I think looking at courses critically is a difficult combo of head and heart. If you think Dornoch's 7th is as good as the best of Nairn than you are not using your head enough - tee hee.

There is no question I would rather play Brora over Nairn. It seems a reasonable conclusion to draw if I think both courses are about equal in quality and Brora is half the price.
BTW - from my three visits to the general area, Nairn had by far the best quality greens. In fact, the combo of firmness and speed was right up there with the best I have ever seen in GB&I.
