Ed, I probably should have stayed silent . . . I think this an interesting topic and am sorry to see it end up another Rustic back and forth. Not that I mind discussing Rustic, I just dont want to hijack a thread doing it. So perhaps we need another thread or two . . . I saw you tried, hopefully some who have played both will respond. I may start one or more my self . . . after all, it has been since last week since I annoyed and/or angered anyone.
As for No. 9 there are most definitely different approach options for different pins, but like much else there the 9th green doesnt "dictate" any particular play. Nonetheless, at the risk of causing yet another disagreement, I'll name a few considerations with the pin that many consider the easiest and most straightforward-- The half bowl at the front left of the green.
At first look this seems a good pin for birdie (eagle?) and sometimes is, but in my observation it sure helps to approach from tight to the left hand side. Approaches from the center and the right must take on the sloping front fringe and the bowl walls at an angle. This seems tricky for golfers of all abilities, no matter what the approach distance (or putt). From the right side one is hitting straight up the canyon and can use the bowl walls to keep it relatively close. In contrast, two of the options from the center or right are to drop it into the back right corner of the bowl and use the slope to hold it in there or to hit a bouncing\rolling shot left and above the bowl to roll it into bowl via the backdoor. It gets too complicated to explain by typing. It is best if we just play the hole a few more times and you can see for yourself.
Tommy's graphic is somewhat misleading as it is difficult to tell that No. 1 and No 9 fairway are connected near the first tee, so it is possible (and sometimes preferable) to come in from well right of No. 9.
