In order to improve your chances of reducing 3-putts or worse, you have to figure out the speed it takes to get the ball to or just past the hole. Once you figure out the speed, then your line can be chosen based on speed. I see far too many players that fall in love with the line and never get the speed right. They are either short or long on their misses. Jerry Tucker gave me this advice when I picked his brain a few years ago at a tournament. I also read his book, Symmetrical Golf. It is loaded with awesome information on the short game and putting.
