Studying the best putters in the world can leave you scratching your head… What you'll find is an endless variety of grips, stances, and strokes… all producing the same amazing results!

But despite these differences, there's one thing that all great putters have in common… consistent tempo. Consistent tempo goes a long way on the greens… especially when it comes to judging distance on your longer putts.
