Shivas's fav, the 15th at PB, is probably one of the weaker holes on one of the greatest courses. But, following the 14th (hardest on tour) even a premadonna deserves a breather.
There are back to back holes at Pinon that are often described as weak. I do not describe them that way except to say that, on paper, they look weak. What I find fascinating about them is that they have the wide spectrum in scoring, over time. With water to the left of both greens, and greens that look similar, but are not, the challenge is higher than appears. I've even heard one of them described as "unfair" because of a small shelf that is difficult to hold on the par 5. One's a short four and the other is a short five.(current 13th & 14th). In the original config they were holes #4 & 5. I believe their placement in that round was stronger because they add to the variety and foreshadow the ebb and flow of both motiff and the thought and deception Ken Dye created. Truth be known, if I were the czar I would make these holes the first and last. The finisher would be the short five and would in my mind be extremely exciting because of the thought processies. Making this so, would also kill a few more birds, by having the clubhouse in a better spot and would make the routing work better. The one downside would be the short four starter. With egos and tecno, many would wait for the green and that may not get you your ten minute intervals.
