I'd like to widen either 7 or 11.
I don't much mind the length of 7, for The Masters. Those guys still manage to hit short irons into that green, and I don't believe the member tee has been effected--though it's certainly a different hole with the trees.
But, to me, 11 is the worse crime. The charm of that very long, very difficult hole was previously that the wide fairway did allow multiple ways to play off the tee. Now it's just a very long hole with only one way to go off the tee. And that's true for the member as well as the tournament competitor. Take out the trees down the right and some of them down the left, and widen that fairway back out!
... oh and if I got a third wish? I always thought the trees they added jutting out into the 15th fairway were ridiculous.
