Probably This is the biggest area of improvement for anyone higher than a 12 handicap. It’s all about speed control and reading the greens. See my you tube video for reading the apex of the putt.. for distance control practice a ladder drill 3,5,7,9,11,13,15,17,19, 21,23,25,27,29 ft putts all set up with 14 balls in a row…also practice putting looking at the hole to teach your eyes to see the distance and feel the distance this is the two best drills…especially after you evaluate if this putt is up or downhill.
