Percy Boomer "On learning Golf..."

Just got thru the first couple of chapters of this 1946 classic…purchase via Amazon was prompted by an older thread that had some excepts from the book; really piqued my interest and am thoroughly enjoying it. Already encountered a lot of similarities to our ABS teachings and ideals: force center of the swing, relying on feellings , approaching the ball from the inside, reliance on connectivity of the arms and torso, importance of level pivot, etc… Trying to expand my knowledge base best I can , so spending time reading/studying ‘Five Lessons’ and this book has been a treasure !
