Gimmicky and campy
The title is a big fat lie. You're not going to add anything to your swing, let alone Hogan's genius shotmaking. The ink & paper it's printed on has far more value. It's like the author has gone out to the internet and slapped some information readily available to the public. The book has many photos but they have been published before elsewhere. Your money will be better spent on 5 Modern Fundamentals, Tom Bertrand's "Secret" or Leadbetter's "Hogan Fundamentals". The best swing book written since Hogan's 5 Modern Fundamentals has to be Jim Hardy's "Plane Truth for Golfers".
