Nigel,
I was recently told, while visiting Inverness, that the golf course will be set, nowhere near the back tees.
It looked to me, based on the comments I heard, and the markings I observed, that the course would play at about 6,800 yards, par 71. However, the weather conditions could alter the setup.
Inverness's greens are relatively small, with pitch and contour, the fairways aren't generous and the rough is challenging.
But, with the best players in the world, age 50 and over, playing today's high tech equipment, they could set it up to play longer.
Hopefully, they'll enjoy good weather, and we'll enjoy viewing a good tournament. I only hope that they televise some of the holes on the front nine, like 4, 7, 8 and 9.
The left side of the bleachers on # 18 seemed precariously close to the left rear of 18 green, and this may cause relief/ruling/competitive problems.
