I just don't think that Sand Hills is difficult enough for the pro tour. I think a winning score would probably be in the 20 under region, regardless of the wind. The difficulty that most people would have with the course, it seems to me, is hitting it into the right section of the putting surface to avoid circus putts. Given the length of the touring pros, they would be hitting short irons/wedges into a lot of the par 4's and they would have a two-putt opportunity on all of the par 5's.
The pros also score well at ANGC, no question about it, but the recent changes (lenghth, mature pines creating tunnels) have toughened the course considerably.
I hasten to add that Sand Hills is a treasure. It is one of my top five golf experiences, but I simply don't think it is up to ANGC's standards. The question, remember, was would you move the Masters. Nope, not in a million years, is my reply.
