I use the alignment mark on my putter to reach a spot on the line between myself and the hole. After reading the line I find a spot as close to the ball as possible to putt at, or sometimes I need to be within a 1/2 inch, or what ever, of that spot. The trick for me is to find my line, get a feel for the distance, pick the spot and then let her go without too much undo thinking. My putting has been very good so far this year.
