"The 15th green spoils the party being so huge."SERIOUSLY??? The large, well contoured 15th green is what makes it such a good (and challenging) short par-4.
#15, combined with #5, gives Dornoch two
very good and
very different short par-4's.
But, as the saying goes, there is no accounting for taste.

Please note I make no claim regarding Dornoch's stature among the better & best courses in either GB&I or the world. Having played the course 400+ times by now, I clearly am a little biased in that regard.
