Dan, I agree completely re the opening stretch of par 4s. Four brilliant holes, each completely unlike the others. I think that's the real wonder of the front nine: every hole flows into the next one, and feels like it belongs exactly where it is in the round, but no hole feels in the least bit repetitive. I can't think of too many other courses that pull off to the same degree.
On 11, I don't like the look of the bunker in front of the rock on the drive. It just seems to me like it doesn't belong there, especially because it's so elevated over the bowl in the fairway. But that's just my idiosyncratic preference. My real quarrel with the hole is that you really don't gain anything by trying to do more with the tee shot than hit a three iron (or a three wood, depending on how long you hit it) straight at the bunker and let it roll down into the bowl. Going further right makes the tee shot immesurably harder, but unless you get lucky it makes the angle to the green worse, which to me more than offsets any benefit from being closer. And the tee shot into the bowl just isn't a very testing shot, because everything slopes down that way so a 20+ yard miss in any direction turns out okay.
I still think it's a good hole -- just not as good as 1, 2, 3, or 6, say, and not at all in the same class for me as 8, 10, and the new 12.
A few weeks ago, there was a discussion about great three-hole stretches. I think 2 through 4 at Yale has to be a leading contender in the race for the best three hole stretch that isn't even the best three hole stretch on its course -- because 8 through 10 is clearly superior in my mind.
