The OZ.1i HS is the first Lie Angle Balanced putter L.A.B. Golf has built with a heel-shafted look. It takes the company's zero-torque idea and puts it in a shape most mallet players will recognize at address.
What's new
L.A.B. Golf calls this its first heel-shafted Lie Angle Balanced putter. Getting there took a riser hosel made of aluminum, which weighs 18 g where a steel version would weigh about 40 g, and that saved mass lets the head stay balanced with the shaft set off to one side.
The body is 6061 aluminum with a Type-3 anodized finish and a fly-milled 303 stainless face insert at 3 degrees of loft. Tungsten weights in the heel and toe bring the head to between 360 and 400 g. Stock lengths are 33, 34 and 35 inches, with 2 degrees of forward lean or none.
How it plays
Accuracy grades out at 8.9 and forgiveness at 8.8, the two best marks on its card. In a 2026 test of 37 zero-torque putters it scored 76.6 and tied for fourth, and the expert testers chose its design over every other head in the field.
Workability lands at 8.6, helped by a hosel that adjusts across 10 lie settings from 65 to 74 degrees. Feel comes in at 8.4, a fair result for an aluminum head with a milled steel insert.
Where it lacks
Human testers and the robot disagreed. Rolled mechanically in a separate 2026 test, it finished 22nd of 26, and the expert panel ranked its stability only 10th in the category even while rating it near the top overall.
Value sits at 8.0, the lowest score here. The stock putter is not cheap, a custom build adds about a fifth on top, and distance control at 8.3 trails the accuracy numbers.
“It looks like a heel-shafted mallet and keeps the zero-torque balance. Testers clearly wanted one.”- The Club Stand gear team
Reasons to buy
- Tied for fourth of 37 putters in a 2026 expert panel test of zero-torque models
- Testers picked it as their favorite design by a wide margin
- A light 18 g aluminum riser hosel comes in 10 configurations covering lie angles from 65 to 74 degrees
Reasons to think twice
- Finished 22nd of 26 when a robot rolled the putts in a 2026 zero-torque test
- Going custom costs roughly 20 percent more than buying it off the rack
- Tungsten sole weights sit low in the head, which will not suit every stroke
