I wouldn't alter a thing. Here is the deal. If you are a left aimer you will have trouble on right to left putts. If you are a right aimer, you will have trouble on left to right putts. So the secret here is to fix your aim.
You are probably a left aimer....so follow this course. To the putting green you go with balls and putter. Find an eight foot putt that is left to right (needs about a cup of break). Next, CUT THE BREAK IN HALF...meaning if it breaks a cup, play 2 balls of break and practice. THE CATCH IS YOU CAN'T MISS IT LOW AND YOU CAN'T HIT IT TOO HARD. After about ten minutes you will be feeling some stuff.
