I've covered the whole "Old Course vs. New Course" thing in my book and on this website countless times previously, but to quickly recap: Tom, the Old Course *is* easy when the wind doesn't blow - at least it is during your first 8-10 times playing the course, when you don't know where all of the bunkers are yet and you can hit your drives without fear. Your first time around, it's entirely possible to get lucky, hit no bunkers off the tee and feel underwhelmed by the architectural experience. But as someone who has played TOC more than 30 times, now, you'll just have to trust me when I say that once you play it enough to get to know it (assuming you've kept an open mind through the entire process), TOC grows on you unlike any course in the world. If that doesn't work for you - i.e. if you have to be able to figure out a course on the first or second pass for you to consider it for greatness - then so be it, but at the end of the day, it really is your loss.
Anyway, re: Dornoch and other courses in predominantly windy areas like it...which is the greater sin: making a course which is too easy when the wind doesn't blow, or making a course which is unplayable when the wind does blow? Of course Dornoch is there to be had in no wind - the greens are big, the fairways are mostly wide, and anyone capable of routinely two-putting from 60 feet on tricky greens is going to be able to suffer most of his mistakes gladly. But even in those conditions, the course retains an incredible amount of strategic and shotmaking interest, to say nothing of remaining just as beautiful as it is in no wind. In a stiff wind, Dornoch becomes quite difficult, but by no means impossible. In contrast, courses like Nairn (with gorse tightly flanking every fairway) or The European Club (with steep, hairy dunes tightly flanking every fairway) lose points with me because if the wind blows and you're not striking the ball crisply, you're going to wind up looking for more golf balls and playing less actual golf. I had no fun at all playing TEC, because my day more closely resembled a mountaineering course than golf - and I'm a decent golfer, at least nominally. Difficulty on a golf course is all well and good, but courses which pursue it to the point of alienating double-digit handicappers can never be truly great (i.e. 10 on the Doak Scale), as far as I'm concerned.
