I like the new book. The things in particular that Mr. K expanded on were the Endless Belt which is cool. There were a couple of place where things were mentioned but not expanded upon . . . example - the "Tripod" is defined but he never actually used the term Tripod that I can see. Also, he in 10-9-A I believe the Lagging Takeaway is mention but there is nowhere that I can see where it is defined.
Overall I think it is in the top 3 editions with the 3rd and 5th rounding out the top 3.
So would I B-Ray. I have been collecting books for years. I deal with golf collectors all the time. I am still looking for a hard cover of that elusive third edition . The trick is to find someone that already has it, and get a photocopy .
