Guys, Yes, its true that they practice much more than we do. And they have the best feeling putters available - A Cameron with genuine German Stainless Steel costs in excess of $5K.
But, also remember that they play EVERY WEEK on outstanding greens that are almost always running at the same speeds, double cut, double rolled, smooth as silk, so it does get easier when your green speeds are ultra consistant all the time. As for the rest of us, unless you belong to an elite club, we face different speed greens every week, sometimes they have not been rolled for a few days,etc. Given this, I agree with the other guy who said they arent as good as we all think, and the stats show it.
