Inspired by mvmac's posts in this thread -- http://thesandtrap.com/t/54372/amateur-vs-pro-putting-stroke -- I went out this morning to check my own setup.
A quick recap: Mike Shannon says the best putters on tour almost always have 1.) A "spine angle*" between 111 and 118 degrees 2.) A right arm angle** of less than 135 degrees, ideally around 132 degrees -- with the shaft and right forearm on the same plane from a DTL view.
(* Measured from hairline at back of neck, to belt, to heels. ** Measured from tip of shoulder, to middle of arm at the elbow, to fingers.)
From a face on view, good putters will typically have the shaft pointing between the left ear and tip of left shoulder.
Looks like I need more arm bend and less knee bend which, it seems to me, is going to require a longer putter shaft. Ball and hands also need to come forward quite a bit toward the left foot.
Here are the links to the full Mike Shannon videos. How freaking great is it that you can get this sort of information for free? I love the Internet, generally, and the Sand Trap, specifically. Im'a go make some putts!
