I was thinking about an artical from ages back on putting

Putting - Identify pressure point that gives you best feel
I use the standard reverse-overlap grip,which is a popular choice among fellow professionals. But more important than the actual mechanics of the grip is the fact I focus on maintaining a pressure-point in the right hand - specifically the right forefinger.
When I place my hands on the club I get a tremendous sence of feel from the right forefinger, and I try to maintain a nice relaxed grip pressure throughout the stroke that allows that feel to flourish.
This is important on all putts. ON the longer approach putts a good sense of feel assists you in rolling the ball the desired distance to the hole; on short putts, that sence of feel help you to keep the putter -face square to the line as you strike the ball towards the hole.
