Yes. I plumb-bob pretty much every putt. For those who don’t know what plumb-bobbing is - stand about 10-12 feet behind the ball in a direct line from yourself to the ball to the hole. Hold your putter vertically by the fingertips. Once you have lined the putter up with the ball and hole, close one eye (usually the left eye) The relative position of the hole to the ball will then change. This will give you a pretty good idea of the break of your putt. It works for me.
