9/29/13: I received a good report today from a club pro. He has had my book, There is More to Putting than Meets the Eye for 2 years. He said he read it a little, but recently his putting just got worse and worse. So he picked up the book and read about aim and the routine. The result was the best putting in 2 years and more birdies in competition last week than he could remember.
I think the nuggets in the book are the chapter on routine, specifically the aim.
