Ed,
I played #2 yesterday and today from the white tees. The course is absolutely unreal in both its beauty and quality. I personally believe that after C & C's work the course is superior to Pebble.
On hole 4, the whites are 471 yds and the Open tees are 569 yds (all numbers from scorecard). The 4th hole is rated #15 on the course. The Open tee box is 15 yards right of the whites. The Open tees provide a better angle of attack and lessen the odds of a ball rolling through the fairway into the waste area on the right side. A long drive to the fairway yields an open 2nd shot to the green, which is a substantial defense all by itself. Moving up to the white tee for instance creates more problems for long or errant drives and if the second shot misses the green, the odds of bogey rise significantly.
On hole 5, the white tees are 425 yds and the Open tees are 476 yds. This is the #1 rated hole on the course. The new tee has already been built. My caddy thought that the new tees added 50 yds to the current Open tee markers. The new tee box is about 10 feet higher than the other tees. The fairway slopes dramatically to the left to a waste area with pines. The green is elevated and the front left has a significant drop into a bunker. You don't want to be left. This is the only hole on the front nine that can reasonably be turned into a par five. 1(406),3(389) & 7(429) are too short. The 2nd(503) is easier than the 5th. It is flat, has an easier (open) approach and less challenging green. The course is a par 70 for the Open, not the normal 72.
I suspect the net effect is that scores will be higher with the proposed changes than they would be without them.
As far as wanting to play the holes as under the conditions that are proposed instead of the current setup, it's a no brainer; I'll play it as it is.
