Absolutely why you should get a custom putter fitting...
I posted a few weeks ago about searching for a new blade putter and was looking for suggestions https://forums.golfwrx.com/discussion/1745480/the-great-blade-putter-search-of-2019/p1.
First, I want to say thanks to all who chimed in. But this is a story about why a putter fitting, without a doubt, should happen when buying a putter.
Prior to my first-ever putter fitting today, I had always played a blade with a plumber's neck (A Ping TR Scottsdale Anser 2, most recently). Going into the fitting, I figured I would probably be looking at a similar model with maybe a different offset type to improve my poor putting scores (usually always 36 putts a round). Boy was I wrong.
After a thorough fitting, my certified fitter concluded that my slight-arc style was actually very slight and that the anser-style blade was actually a detriment to my natural stroke. Instead, I was fitted into a center-shafted blade with only a 1/2 toe hang, which I never anticipated that much of a change. I became comfortable with the Bettinardi Studio Stock 28 Slotback Center Shaft, and as long as I was aligned to my target and the ball was in the center of the blade, my putts started on line nearly every time.
SO, if you haven't been, do a putter fitting before purchasing a putter, especially if you plan on spending a lot of money on it. As for now, I anxiously await a phone call from the retailer about my new investment's arrival, and I'm sure I'll provide some updates about if the tool is making the operator's scores better.
