he just goes at it too violently
I agree, and IMO it has cost him some tournaments, even some majors.
I've always wondered why he doesn't hit that "stinger" more often. He doesn't get nearly as violent, he practically hit's it down the sprinkler line every time, and it's repeatable.
I think Tiger hit's some of his best shots when he saws off his finish and shortens his swing. He can hit that stinger with a 3 wood 300 yards and it's right down the middle, and that is a sawed off swing. Why on Earth he doesn't play that shot more often is beyond me.
