I much prefer the look of the bunkering at Royal County Down (which one poster described earlier this summer during the Irish Open as "scruffy little sand pits") to the revetted bunkering seen at many courses in Scotland. I thought the bunkering at RCD looked much more rustic, natural, etc. than the revetted bunkers, which seem too artificial, at least in my opinion.
Full disclosure, I am basing this view solely from watching the courses on television. I have no clue how they play.
