Spieth is the betting favorite. Augusta is a different animal. Putting and short game there are really emphasized. I don't trust DJ when he has many 6-10 foot par putts and driving accuracy isn't as big of a deal in Augusta. I like Spieth to get it done this year. As you said the course likes to give repeaters to players in a short time.
And a delicious carbonara it was! Hey I took Molly with her learners permit out past Stoneleigh this past weekend. That course is like a magnet because I found myself telling her to make the turn off Rt 7 to cruise around the side streets a bit.
Don't forget the Duck Donuts and the kid(s)! :)
I only want to quibble with one thing you said. This is a pet peeve of mine.
"Doing the same thing over and over again and expecting a different result" is not the definition of insanity, in spite of Einstein saying it.
