"And, how much further left would you go if it was up to you and TE?"
Pat:
Personally I wouldn't go a single yard or step further left on #7 for a number of reasons.
First, the old original Flynn tree is right there in shape and form--it was simply let grow and became overgrown over the years and apparently forgotten about. Up until about five years ago there was a medium sized tree right in the middle of it that was removed when the hedge to the right of the Macdonald/Raynor tee was removed recently.
Second, from that seemingly inconsequential shift left the shot into the green changes noticeably as the right to left bolster of the green cant really takes effect on holding the ball when it hits the green. A normal straight shot at the green does not appear to get anywhere near the riccochet or skidding result that casts the ball long and left that seems to happen from the Macdonald/Raynor tee just seven steps to the right, particularly when the green is very firm and fast. From the Flynn tee the shot once it hits the ground becomes more "redanish" in bounce and roll.
Third, it is actually possible to get a ball on the green by playing a very low running shot up the rather severe upslope of the approach fairway and if a tee was farther left the angle and runup ability on that shot probably wouldn't work well at all.
Fourth, there's an old original maintenance road immediately to the left of the Flynn tee (by about one step) and if a tee were build left of the Flynn tee that road would have to be moved left which would start to jumble it and the new tee up with the 4th tees, particularly with play from the new US Open tee on #4 that is app 40 yards behind the original 4th tip tee.
These things need to be considered from numerous perspectives. Your new thread about good and bad tee placements would very much come into play and rather quickly on a hole like this one.
It's a digression to mention but through the 2004 Open tee length addition and recently on hole #8, in my opinion, the club has done a really thoughtful and excellent job of positioning the height of tees as they should be particularly in this lowland front nine section. I'm sure there's always the tendency these days to raise tees off the ground too high to simply establish total visibility on what's in front of you and the club avoided this inclination really well.
If the club does decide to reestablish the original Flynn tee which is not a sure thing at this point, the next question would be if the Flynn tee should be melded into the original Macdonald/Raynor tee or reestablished as a separate tee immediately juxtaposed to it.
This question actually came up. One important opinion was that the Flynn tee should be reestablished as a separate tee immediately juxtaposed if for no other reason than that's the way it was done in 1929 and at this point restoring it that way again tells a fairly interesting story of the evolution of the golf course. In other words, it would be redone exactly the way it was undone---which in restoration can be a pretty cool way to go.
