Zero-torque putter technology of the recent past has been beneficial, but at what cost – requiring oversized, garish heads. The all-new Odyssey S2S Tri-Hot Rossie is here to change that.
Odyssey’s zero-torque lineup is expanding in 2025, with the Square 2 Square family welcoming four new members. With the Odyssey S2S Jailbird, S2S Max, and other select models being included in our best zero-torque putter of 2025 and overall best putters of 2025, the S2S Tri-Hot range needs to hit the ground running. With the new Odyssey S2S Tri-Hot Rossie, taking inspiration from the Odyssey Ai-ONE Rossie S Putter as used by Jon Rahm, they’ve done that and then some.
Coming in with a premium price tag, the Odyssey S2S Tri-Hot Rossie stands out from the pack straight away – the elegant red and black colorway to the compact mid-mallet head, this feels like a perfect middle ground for the golfer looking to enter the zero-torque scene without sacrificing the traditional nature that some putters posses.

The R&D team at Odyssey have clearly been on a mission to make zero-torque putters more accessible to a wider range of golfers. Traditionally, this category has been dominated by unorthodox shapes and extreme designs, with onset levels that can feel alien to anyone used to a classic blade or mallet like the Scotty Cameron Super Select.
Zero-torque putters often require a significant amount of shaft lean to position the center of gravity far enough forward for the concept to work. But with the Odyssey S2S Tri-Hot range, things take a more innovative turn. Thanks to a clever multimaterial construction engineered by the R&D team, Odyssey have been able to move the CG forward without resorting to that somewhat exaggerated lean.
To put it into perspective, the L.A.B. DF3 features 1.29 inches of onset, while the Tri-Hot Rossie sits at just 0.41. The Rossie still carries that slightly unconventional look, being center-shafted, but its compact profile and reduced onset make it far less intimidating over the ball. It’s a design that welcomes traditionalists to give zero-torque another chance, without having to reinvent their stroke.
The biggest leap forward, however, comes at impact. Odyssey’s familiar Ai-ONE insert has been replaced with the new Ai-DUAL, a dual-layer urethane face that blends a softer outer layer with a firmer backing. The result is soft and responsive, but with top spin optimized throughout the face, leading to end-over-end roll throughout.
Variable face thickness across the insert ensures consistent roll, while the 19-degree sloping grooves are more aggressive than before to ensure roll is consistent and feel is solid. It’s an evolution that not only enhances distance control but also delivers the best roll we’ve seen yet from a zero-torque design.
All S2S Tri-Hot models feature a standard 72-degree lie angle, which I’ve noticed is traditionally 2 degrees more upright than many rivals. In previous Odyssey putters, this could make the face appear slightly closed, but with the new shaft placement sitting closer to the head, the setup feels more neutral and confidence-inspiring. And if it’s not quite right, custom fitting options remain available.
All standard-length Odyssey S2S Tri-Hot models come with a KBS SL120 Black shaft, which is heavier and stiffer than previous models. The all-new Pistol Plus grip is larger than before, with more aggressive angles to complement the putter and allow the user to feel the grip more in their hands.
Distance Control and Roll – 5/5
The Ai-DUAL is the focus here, and from my on-course testing, I’ve been blown away by the performance of this insert. Think of the TaylorMade ZT, with the pure roll insert, on steroids. It’s not often you can note a clear difference straight away during testing, but with the Odyssey S2S Tri-Hot Rossie and all other Odyssey S2S Tri-Hot putters, I noticed the roll being incredibly true in relation to my stroke from first putt.
I was fortunate enough to test the club at Mannings Heath Golf & Wine Estate on the Kingfisher course, with USGA greens challenging enough to torment even the most accomplished golfer. The ability to see my ball rolling, how it’s actually supposed to, took me back to begin with. I was almost questioning how it can be rolling end-over-end, considering I’m someone who notoriously struggles to maintain an optimal putting stroke.
I pushed this test further by intentionally hitting the ball on the heel, on the toe, low on the face: areas that absolutely shouldn’t be promoting top spin.
Yet I’ve watched that same pure, end-over-end result occur time after time – I did notice it wasn’t as optimal lower on the face, but by laws of physics, this is understandable.
I do feel it’ll take a little time for many of us amateur golfers to get used to this new performance level, as the purity of roll can be surprising at first. I’ve certainly watched the ball travel further off this putter face when applying the same amount of force from my own gamer.
Looks, Sound, and Feedback – 4.5/5
Let’s face it, zero-torque putters look odd. There’s no way to shimmy around it – for the traditional golfer who is used to the elegant looks of a blade, putting a large, wacky style like any L.A.B putters down may lead to some skepticism.
Personally, I’ve always struggled with it.
The Odyssey S2S Tri-Hot Rossie does attempt to look more normal than other ultra-low torque models, and achieves that to a certain extent. I would say it removes a similar amount of that unorthodox feel as the TaylorMade Spider ZT does. At first glance, I thought it was quite bizarre, but after extended use, it feels slightly more natural – especially to someone who doesn’t like the larger mallet.
In regards to feel, the Ai-DUAL insert gives off a notably different sound, and thus feel to the previous Ai-ONE; it’s a lower frequency, slightly duller, and to my stroke felt softer off the face during testing, even with a variety of different golf ball models.
This pushes the new, modern Ai-DUAL closer to the White Hot insert of years gone by – a fan favorite for many a gear nerd out there. This is a welcome change in my eyes, as the White Hot insert was such a strong asset to Odyssey- they didn’t need to change it!
Final Verdict – 4.5/5
The Odyssey S2S Tri-Hot Rossie slots into the zero-torque mid-mallet scene with the likes of the L.A.B MEZZ MAX, the TaylorMade Spider ZT, and many more.
What I think separates this model from its rivals is the new Ai-DUAL insert. The ability to provide end-over-end roll is not something many putters can do, and although the TaylorMade Spider ZT comes close, I would say this outdoes it.
That being said, this does come at a very premium price tag – something that I would want to see a lot more customization with, like L.A.B.
It won’t be going into my bag for now, but the S2S Tri-Hot family could certainly feature in my setup next year.
