since I've only played Cruden Bay a couple of times, I'm no expert on the value of the changes, but I played it about a week ago in a Mixed Greensomes, with my 70th birthday less than three weeks away and a stiff wind to contend with from the third tee onwards, i hope I never see the medal tees again.
On the holes into the wind, I think we only played my tee shot on the eighth, in fact it may have been the only hole I got a ball in a place we could play from.
My recollection from the previous round, in 2006, was that the course was difficult, but not THAT demanding. Of course, i didn't play the medal tees and I was only 58 years old.
The upshot? we shot 55 going out, and were bested by our fellow competitors by 12 shots. Turning back we managed a 43 despite a lost ball, and bettered them by one. A pair of 43s would have put us near first place
