Ok to study 6th edition?

[12 piece bucket]

The sixth edition was invaluable in preparing for and getting my G.S.E.B., in Feb. 2007. The test and study materials are mainly based on editions prior to the 7th edition. Due mainly to Mr. Kelley's sudden passing. My guess is that he updated the material for the book, before he was able to update test and study questions.

The main difference, in my observation, between the 6th and 7th edition was that some material had been moved from one section to another, and the wording of some passages was changed in an attempt to clarify the topic.

The overall concepts of The Golfing Machine are very much intact. In fact, my 6th edition is still vry much in use today.

To me (other than the big debate on the shoulder turn component) the big changes in the 7th are in the Flail Section in chapter 2 and the endless belt additions in chapter 6 in the aiming point part (not sure where aiming point is exactly but it's 6-E-sumpin'). Mr. Kelley has some invaluable stuff on Endless Belt in those to sections. MUST READ STUFF.
