Getting the chance to review these putters is a bit of a coup for the blog. Putter nerds like me will likely already know about Breakthrough Golf Technology and their revolutionary "Stability Shaft". That shaft has been on the market for several years and has found many fans (and imitators). It was one of the original extra-stiff, low/no-torque putter shafts and uses an innovative multi-material design. Several putter companies offer the Stability shaft as an upgrade option, and it's also a popular after-market upgrade. It's a brave decision to go into competition with your customers and release a putter of their own. They must be convinced they've got something that can stand out in an increasingly crowded zero-torque marketplace, and that makes it worthy of review. Thanks again to Adam at Auchterlonies for giving me the opportunity.
