I don't but my coach told me of a guy who struggled with his putting. He checks your best position to see a straight putt using a laser...the laser points direct to the hole and orange dots mark the line. You then take your putting stance and look at the line to see if it still looks straight. If it does, fine, if not then adjust your eye position over the ball until it does. All to do with eye dominance and vision basically. This guy simply could not see the line straight until he suddenly turned round and took his stance left handed! There and then he bought a left handed putter and never looked back!
Today I got 3 others and myself putting one handed on the practice green.
There were plenty of putts that we'd all have been happy with 2-handed.
Try it next time you're on the practuce green
You might be pleasently surprised....
