Larry,
I still have some questions on plumb bobbing. I have your book and have applied plumb bobbing into my gsme. I like how it gives me a line to putt along. Here is my question however. If I stand behing the ball and plumb as you suggest (dominant eye lining up the ball to the hole) I get the line and it tells me if the putt is straight or is going to break. The problem that I see is if I am not directly behind the ball. If I think I am behind the ball but happen to be a bit left or a bit right the break is going to be seen differently.
