Wayne,
I agree. The firm and fast ideal as applied to Augusta would probably shrink the list of "realistic winners" even more. The reason that I think you're dead on about Tiger is 2-fold.
First, he has the ability to hit his iron shots extremely high. That, coupled with his extra length off the tee would allow him to be hitting 2-3 clubs less than Fred Funk or Chris Dimarco and could help him hold the greens easier or give him a more forgiving recovery shot.
Secondly, I think that Tiger's short game/sand game/general recovery game would allow for him to save strokes when shots took an unexpected bounce and ended up in a less than ideal situation.
In the end, I think firm and fast for ANGC is the correct setup, but I think the extra length is going to have the opposite effect than intended. Instead of challenging the longer hitters, it's only going to kill the shorter hitters.
An interesting setup would be firm and fast but also 20mph+ winds. Imagine trying to hold 7 green with a 20mph wind at your back, some others as well.
Hopefully the tournament stays interesting and doesn't become a U.S. Open in the sense that birdies are extremely rare.
Just some thoughts.
