Stability limits unwanted movement by stiffening the shaft by 25% without abolishing feel and reducing torque by almost 50%, to deliver the club face squarer at impact. It was exhaustively tested with hundreds of putters using state-of-the-art high-speed cameras, robots, SAM Putt Lab, Quintic Ball Roll software and Trackman4.
Our objective was to isolate relatively small face movements that affects ball roll. Regardless of how well golfers’ putt, there is the human error factor that skews results. Our focus was on the putter face at impact then details ball roll till conclusion; we hit thousands of putts featuring a variety of head designs and weights to draw precise conclusions.

The Stability design was extremely challenging; invent a shaft that had the same weight as a traditional steel putter shaft but without being too stiff, heavy or having a deadened feel. It also had to mitigate unwanted flex and twist.

“When developing Stability our objective was to isolate the small face movements that affect ball roll. We specifically zeroed in and analyzed the putter face at impact; thousands of putts were hit with a variety of head designs and weights. The result was a reinvention of the putter shaft from the ground up.”, states Barney Adams.
