Putters are a personal thing to most people, but the most important investment you will make. I can say that the Odyssey DFX 2-Ball is a great putter for tentative putters or people who lack confidence to hit the ball. If you have been leaving your putts short this is the putter for you. It has a hard surface so you do not need to hit the ball as hard to make it travel. However remember one thing if you have been playing on fast hard surfaces, then you should think about a putter with a softer feel. So has my putting improved? The answer is yes. I had the Nike Oz putter before and it was OK, but does not come close to the Odyssey DFX 2 Ball putter. Try it and compare the two as it would be interesting to see what others think. The two balls on the head do help you align the ball. However they do not help you straighten up a bad putt. I have pulled a few putts, but on the whole this is the best putter out there for me anyway. Remembering I live in England and hard fast greens are as rare as the dodo - basically extinct. So go out try the Callaway Odyssey DFX 2-Ball. I think you get to love it as much as I have.
