I am attempting to switch putters bc I have been missing close putts bc I open or close the face to often. Been trying to fix but read the zero gravity center aligned putters help to keep face aligned and not moving. My dilemma; went to look at putters and some where $500 Taylor made spiders 38 inches, and used were still $390. So how do you practice to see if you want them wo blowing 4 to 500 dollars?
