That's not a problem of balance, but of putting with an aiming line. I've had the same problem. Yesterday I finally heard an explanation of Jim Furyk's strange putting routine, and it seems to be designed to combat exactly that issue. He stands over the ball for a "pre-read" impression. Then he reads the putt from behind, biased by what he felt over the ball. That way, when he gets back over the ball, he won't be surprised into second-guessing.
If I ever go back to lining up the ball, I think I'll do that. (As if golf weren't slow enough already. Yechh!)
Cheers!
