A putter can sit perfectly behind the ball and still feel all wrong once you start your stroke. That’s what makes Odyssey’s new TRTL line interesting. The putters share an unusual hexagonal mid-mallet shape and those easy-to-spot twin white alignment lines, but there’s more going on than looks. Four removable weights at the corners give golfers another way to dial in the feel.
The standard TRTL is $349.99 in the U.S., with three neck options: the crank-hosel CH for a slight arc, the short-slant S for more toe hang, and the face-balanced double-bend DB. There’s also a bigger, $399.99 Square 2 Square TRTL Max with a low-torque, toe-up setup. Odyssey lists November 6, 2026, as the start of shipping for preorders. And while PGA Tour golfer Min Woo Lee has used a TRTL prototype, that doesn’t mean one will suddenly cure your three-putts.
Start With the Neck, Then Adjust the Weights
Here’s where choosing the right version matters. As Callaway explains in its putter-fitting guide, a golfer with an arcing stroke may prefer some toe hang, while someone looking for less face rotation may get along better with a face-balanced design. The TRTL’s different necks give you those choices before you even touch the weights. Then you can adjust the four corner weights to shift the center of gravity toward the heel, toe, front or back and fine-tune toe hang. It’s a useful extra adjustment, but it won’t replace trying the right length and seeing whether you can aim and start putts where you intend. Odyssey also sells additional weight kits separately.
Before You Order
- Standard TRTL models start at $349.99; the larger Square 2 Square TRTL Max is $399.99 on the official U.S. pages.
- The Ai-Star insert uses a urethane striking surface over an aluminum layer; Odyssey claims consistent ball speed, which we have not independently measured.
- Model availability, handedness, length and the feel of the insert should be checked before ordering.
We haven’t putted with these ourselves or measured how consistently they roll the ball. Before spending $350 or $400, we’d want to try a few versions alongside a familiar putter, ideally during a fitting. A clever weight system is worth exploring, but only if the putter feels right and helps you start the ball on line.
A Putter You Can Actually Fine-Tune
What we like about the idea is that you can choose a neck that suits your stroke and still experiment with the weights afterward. That makes the TRTL more than just another oddly shaped putter. Whether those adjustments help your game is something you’ll have to find out on the green.
