King's Course is the better out of the 3 layouts at Gleneagles in my opinion. Like you said its an older style James Braid layout, was the gorse out in full when you played?
Gleneagles is the home for the 2014 Ryder Cup which will be played on the PGA Centenary Course which you would have seen beside the practice ground at the bottom of the hill. A bit of a monster that was designed by Jack Nicklaus and as such has more of a man made look about it.

Im with you Alex, in fact I think I could play the King's course for the rest of my life and be quite happy. I was very impressed. A little piece of golf heaven in the Highlands.
