Great thread. Thanks for bringing it up again. I have improved my putting tremendously. I used to ave 33-34 ppr; now it is 29-30. First, I draw a line around the entire ball. At first, the line would wobble when I putt. I kept at it and found a way to the line rolling end-over-end in a straight line. I found that it helps when you take the putter a little inside on the way back. Then the forward stroke is coming from the inside as well like playing a little draw. Second, I putt with a square/closed stance which helps you take the putter to the inside on the way back.
