I've played in all the US Opens excepting the first one in mid 2009. Not all of them were the four rounders that we have today but I can never recall WGT moving the tees around on any of them.
They have changed the wind speed and green speed, but to my admittedly not great memory, I can not think of a time when we didn't use the same tees for the Qualifier and every round of the Open thought last year at Pinehurst.
If they move the tees around, it makes your course notes pretty useless which I heavily rely upon for new courses. Green speed is bad, when it goes between fast and championship, if they vary all that stuff the scores will suffer.
Since the cut moved to 55, we probably lost almost 100 players who would have been in the tournament. I really wish that WGT would allow anyone within 5 strokes of the lowest score into the tournament and have a cut after round 2 of the Open, maybe only pay the credits to those who make the cut.
