In pics 3 and 4 the head is in a different position, centered for the shoulder stroke and tiltted in the arm stroke. SHould these be different? Can you center the head for arms only?

Bgolfing,

The head should/can be centered in both strokes. Sorry if you see any distortions from that "sameness."

Lie Angle
 

VJ - I have noticed that many more players have the toe slightly off the ground (as opposed to the heel). If there is an error in the lie angle of a putter, is it better to have it slightly more upright than down? How important is it to have the lie precisely right?

Thanks - Bruce

Dealing with aim.....the lie angle of the putter is the utmost of importance. Having the toe up will result in left aim...having the heel up will result in right aim. That is...until the computer compensates for it either in aim or stroke path or hinging or.......all three or.......none at all.

To answer the question: Get the putter sitting level!

Thanks VJ - Bruce
