Well, you know they say a mind is a terrible thing to get involved a golf swing. I guess that goes for putting too. It's like math tests, your first guess is the best. Since your results usually prove out your chosen line, just trust what you've chosen and don't over think it. A golf psychologist told me to try and create a break between the left brain activity of figuring out the line, etc. and the right brain needing to take over to make the physical swing (putt). He recommended a "cleansing breath" (as it were) to facilitate the shift. Just my $.02.
