Most pros use a fairly upright stance when putting, and a lot of the books, videos, etc. say you should have an upright stance when putting, with your eyes over the ball, etc. But Niclaus was hunched over and plenty of other great putters hunch over the ball. I was just wondering if there was any scientific proof or otherwise which proves a more upright stance is better. I suppose a hunched stance puts a curve in your shoulders, which might not help. I know a lot of you will say, 'It's whatever you're comfortable with', but scientifically one way should be better than the other.
