YJ,
It's happening everywhere and for every mode, i.e., stroke play, CTTH, etc.
Where I really notice the change is at St. Andrews. For example and especially hole #'s 3, 6, & 7. I will land my drive, say on #3 within 85-90 yards to the pin. Before the course release, I would use my 60 degree Z Wedge (90 yards, and full BS) and usually land between 1 to 3 yards from the pin. But no more, same shot technique is now making me land 5-8 yards from the pin, if not more, and I don't understand why. I actually had to abandon my ready go tournament a short time ago, because my meter would freeze up practically on every shot. I tried to buffer it by taking practice shots but to no avail. Before I logged on prior to play, I did clean every one of my caches, the browser, the flash cache, and the disk clean up tool.
I don't know, but something is seriously wrong with my play since the release.
Thanks,
Track
