I recently purchased "Search for The Perfect Swing" by Alastair Cochran and John Stobbs, and as I've been reading this text I am quite surprised by the similarities between it and TGM.
I looked at the copyright date and it's dated as 1968.
Is anyone else on this site familiar with this text, it's quite surprising that some of the same conclusions were reached in the same time period in two different parts of the world, the U.S. and Britian.
