Choosing your putter is like finding your partner that you want to spend the rest of your life with, and you better be willing to stick with it through the high times as well as the low times. I hope you did not choose your putter just because it looked good. And God forbid, I hope you did not take it just because of the price :-((
Please, please take your time. Have a few dates with it, preferably on the golf course, because you will get a few strange looks in a restaurant! Roll it through your fingers, twirl it around your hands. If the balance feels good and chemistry ignites. Trust your gut feeling and your instinct. Listen to your feelings. If, for some reason you have difficulty with any of the above, then call me for help!
