Looks like you picked a good ole Scottish driech day to climb McDuff. I'm hearby declaring it to be over 3000 ft, so you've bagged your first Munro, Bob. As I said at ReRo you've got better grass texture than the original. I've just had a word in the ReRo Terragen admin's shell-like about their lengthy pondering over approving / disapproving the tut.
