Within this book Nick Riley PGA Professional, would like share some of his green reading theories and introduce you to his newly developed slope measuring system (SMS). You will learn to see and assess the extent of the degree of slope on any given putt, and, with a little practice on your part, you will soon start to improve your green reading skills and hole more putts.
The SMS works around how the slope on the green changes your body position, this then allows gravity and your putter to guide you in your slope assessment.
