I have read so many golf instruction books that my book case is creaking under the weight of them. Some of them are more exciting for literary content (Ben Hogan, Percy Bloomer) and some are just prettier (Tiger Woods, Phil Mickleson). But I am gaining ever more trust in this one. Firstly, nobody has won more majors than Jack and secondly, his hands are the same size as mine!
His posture is not 21st century and there are others things which go against the current teaching fashion. But I like many of his unorthodoxies. My current favoutite is the ankle roll. Apparently totally no no for now (knees are not supposed to do that) but it helps me so much with rhythm and improves my ball striking for all range of shots.
Everything is clear, well organised and well illustrated. As the title says, it is his way but the 18 major title winner may have something good for you.
