Rich,
I too have spent some time on the St. Olafs. It is good practice and there are some very good holes. I also think that it has some of the best land that could be incorporated into the big course.
In thinking about the changes at Cruden I think some of it could be done with the the following:
#1 and # 2 on big course stay same, then play #6 on St. Olafs ( Par four with drive over hill and green site on the side of hill), then #7 St. Olafs ( short par three, could be stretched abit). Then return to play #, 3, 4, 5 6 , 7, on the big course. Front 9 par 35.
Then play big course 8, 9, 10, 11, 12, 13, 14, then play from 15 tee to 16 green as a short par 4 and finish with a long par 5 from 17 tee to 18 green. Back 9 Par 37.
Could be done without a lot of earth moving.
