TimW:
A couple of quick points.
First, Torrey Pines / South is not that good of a golf course --even with the improvements made by Rees Jones. This I have to qualify from JUST watching on TV. I'll be playing the course later this year to confirm my own impressions. Are the improvements better than what was there. From a distance it appears so.
Second, the layout of Torrey is weak because few, if any of the key holes, actually take advantage of the close proximity to the natural edges of the hills overlooking the ocean.
As a qualifier I would like to know from someone who might have attended if the REAL back tees were used for all the rounds on the South. Too many times you get the listing of the total length in the newspapers but tournament officials will push the markers up on a few holes (i.e. 18th, to name just one).
As far as your take on rough is concerned. I do not find the option of people hacking out SW's back to the fairway as golf. That is taking the penalty of missing a fairway by six feet WAY over the top.
In addition, the element of rough only accentuates the role of luck. People who miss the ball by a few feet may be left with no shot except a pitch out, while those who miss by a mile get the advantage of ground chomped down by the gallery.
Strategic golf courses can be designed that bolster overall shotmaking skills. Hitting the ball straight is one key elelement in any player's arsenal -- it is not the only ingredient.
Let the players play is my motto. Yes, you have to "toughen" the course, but do so in a manner that the winner will really be the person who has played the finest overall golf -- not someone who lucks their way around because they had a lights-out putting week or bunt the ball out there 240-250 yards.
High rough / hay (right off pristine fairways to clarify) is an absolute admission by those preparing a course that they have nothing else to offer. It is also a clear admission, in my opinion, that the existing course has little strategic value and therefore must resort to gimmicks to maintain the farce that a bonafide championship has been contested on that layout.
As far as every day play is considered I think that rough should be no more than 2-3 inches in height maximum. People look for lost balls like the FBI searching for terrorists. And, should someone hit a Pro V-1 in the hay you can be sure they will be looking for awhile to recoup their investment. How do I know this. I can remember many rounds on Bethpage Black in years past when six hour golf was par for the course because of high rough conditions.
I hear what you're saying Tim but let's not confuse the game played by the world's best and the rest of humanity. I don't like the idea the USGA has fallen asleep at the switch. But lengthening courses, with sensible rough, is a good combination for the elite players. Again, from a distance and without having played the course, I don't see Torrey Pine / South as being much of venue for a possible Open -- not when Riviera is an option to consider.
Just an opinion ...
