My friend and putter design mentor, Byron Morgan made these prototypes for me 20 years ago. If you use torque as a definition there are 6 levels of torque. One of which would be considered a "zero torque" option today. It is the least stable and hardest putter to use in this batch. Why? Because there is more to it than just shaft placement, a lot more. There are patents that protect the designs that work. These were built before most of the influencial patents were in place. Mine is not in vioaltion of any of them. That is why it is so hard to use. When you make a putter decision look at the big picture.
