Why does the ball bounce when I putt with my Odyssey White Hot X2 putter?
Difficult to say without seeing you hit some puts and checking the specifications on the putter. If the ball is bouncing off the face, then you could be hitting the ball with a descending blow, causing the ball to bounce. If the putter has too much loft, or too little loft, you could get some inconsistency in the role. Yo should see a qualified club fitter, especially someone that is knowledgeable about putter fitting.
