hi jamesh
i find that with putting i only spend a minuet or so picking the line, i find my first look at the line is always pretty good, i spend more time on working out the pace of the putt.
since i started doing this way my putting has improved a lot. before i would second guess my line and break and found my first line was always closer. like you said the more i thought about the line the harder i made it for me to pick the right line.
