Why do you think a grip has anything to do with your pulls on a short putt? Unless you have the wrists breaking...then yes, a grip might help. If so, start the drills x-handed to kill the wrists. Then go back to your comfortable grip, keeping a light pressure...no death grip at all, no tension...ANYWHERE.

Then with your normal grip get 2 2x4's and do 50 rail drills at your 8 and 16 foot lengths. I guarentee after 4 strokes you will know exactly what you are doing wrong. Then spend the rest of the 46 fixing/engraining it.

A comfortable trusting grip is essential to putting. Switching around, guessing and messing that up in your head will take away from the real problem...your path which is going to be based on setup, shoulder tilt and arm hang angles... Fix this FIRST, then slowly work in a slightly different grip is you want.
