Very good Flat Cat Solution Putter Grip. The Flat Cat Solution is a weighted putter grip that builds on our original Flat1 grip shape. If you enjoy the feel of a square putter grip such as the original Flat Cat but could use a little extra weight to steady your swing, the Flat Cat Solution will assist you in the battle against the dreaded yips. The stainless steel weighted Easy-Glide cone allows you to simply remove the club from your bag.
