This is very interesting. I've never seen that result occur, but of course I take your word for it Andrew (and Tom, I guess I should've known better than to challenge your memory). To be clear, are you saying eagle is difficult, or simply not possible (with a putter)? Architecturally, I think the difference is vast. I've never played Riv, which of course is the prototype in the US, but I guess I just didn't think of this hole as having the same DNA as Riv.
Mike DeVries, if you're watching this discussion, can you weigh in on the genetic makeup of this hole? If we assume that the back left pin placement negates the chance for eagle, we must also assume it was an intentional design. It is surprising to me in some part though, as this is a very difficult pin placement - in fact, I've never seen it in use. I would think that if you were going to go through the effort to engineer this result, and this is one of the only holes at TKC where it makes sense to try, why leave only one variable setting at the super's disposal to engage this feature? Of course all of this is moot if it is used all the time, and my sample size is too small. But at 16 or 17 rounds, I don't think that is the case.
