Did it never happen to you that you see the putter head moving all over the place as you lower it towards the ball. Can be almost a scary experience and you wonder how you'll ever be able to make it more steady for the putt.
So: How?
In my case: Extensor Action
(Personally I just went from Paw to Push basic (with a significant improvement BTW) but I kept the Extensor Action...)
