As partial answer to Pat, the par-thress on the Black are decidedly more variable in both distance and angles than the West. Consider the 14th hole. The tee box is HUGE and very wide. With the new front left tongue the hole can play as short as 130-yards to as long as nearly 190 yards by placing the tees back left and the hole back right. I think everyone is going to be pleasantly surprised as to how this hole plays. By far the easiest in 2002 it will not be now.
Tom, I disagree with your assessment of the third hole, especially with the new back tee. Here again is a large green that runs long and angular to a series of tees that increase their own angles toward the green. It is hole where the smart player learns to play for areas rather hole locations as just a bit of miscalculation can get you into serious trouble short & in bunkers or just long and over the green and downhill.
I think the weakest of the par-threes on the Black is the one that is near unanimously loved by all... the 17th. I'm sure that will surprise many, but it really isn't a difficult hole. The modern golfer, especially the professional, has more problems in accuracy rather than distance. With the green as wide as it is, an accurate shot distance-wise that is straight will always find the putting surface where very few three-putts will happen.
The 8th hole will also be viewed in a new light this year. With plans to vary the tees and with the front putting surface now recovered, the pond is now DEFINITELY in play as will be the back bunker when the hole is back there.
I am also of the opinion that the 10th hole on Winged Foot West is the finest par-three that Tilly designed and is amazing in its subtleties. With a slower green speed for the 2006 Open the USGA was able to use back hole locations, especially the killer one back left. It is a glorious hole!
I believe the two sets offer very different challenges and varieties and that, as sets, they are equal...
