The 12th at Pine Valley makes a golfer think on the tee. What club to hit (there are several to choose from). Unfortunately, what it doesn't have now, but will have as the clearing progresses, is temptation. The tree clearing is integral to the greatness of the hole and increases the mental challenge of the hole. Maybe the physical challenge of the tee shot isn't at the same high degree of other holes at Pine Valley, but it surely was designed as a great mental test off the tee.
The approach shot is not as easy as it appears. The approach is from a fairway that flows seemlessly onto the green is made more difficult for the lack of depth perception. A green that sits above the fairway, even slightly, is somehow easier to get a feel for--at least for me anyway, those that are at fairway level are much harder, such as those at Manufacturers.
And, as Jim said earlier and knows so much better than most, the green is a tricky one that requires a precise approach to have a sure shot at a one or two putt. Three putts are very easy to come by; true of all the PVGC greens.
