Edel was the first torque free putter company to discover that most golfers actually aim left of the target when they set up to putt.
This is primarily because face-balanced and toe hang putters have a built-in tendency to open during the backswing. As a direct consequence, it is extremely common for golfers to aim left of the target, without even realizing it.
This is why Odyssey’s entry into the toe up, torque free putter market failed horribly. They produced a single putter with this technology, and sales were ice cold because people felt that it setup closed, and they couldn’t stop themselves from hitting the ball left of the target.
Fortunately, this particular issue has been addressed by all the companies that still produce lie-angle balanced putters. Ensuring that the putter appears ‘square’ is a key design component at Edel, LAB Golf and Axis1.
