Rory averaged 373.6 yards off the tee on day one. Thomas hit one 400 yards today. Much of the cause is wind and firm fairways. Carry distances do not seem much different from what happens at a normal tour event.
The course appears to providing plenty of challenge to the players despite the length players are hitting it.
I assume a ball rollback is unlikely to ever happen and do not really want a rehash of that issue. I think I have heard every argument that could ever be made on the issue 25 times.
If you set that issue aside, I prefer this type of setup to what you see at the Masters with the greens mowed from green to tee in order to limit drive distance. This setup requires the players to have more control over their ball off the tee and they get rewarded when they have it.
