I use a grip with center of palms [not heel] on shaft to putt. Each thumb straight down the shaft top and even the right index finger on the shaft aft parallel to the thumbs. Always have. Yoda modified it a tiny bit for me, though he didn't know he was, because we didn't work on putting! but by laying the left index finger on top of the three right fingers down the shaft...en voila!you have a Yoda preferred reverse overlapping grip to chip. With a center palm grip Yoda said the hinging action you choose is always pure. Hey! Take a lesson from Yoda and have him show it to you! Great for putting and chipping....
