The Spartus GT Beta represents Spartus’s most experimental step yet, a prototype designed to test new materials, shapes, and grit technologies before the final production model. It’s not a finished paddle, and Spartus has already confirmed that multiple refinements are on the way. Still, after spending more than ten hours testing it both indoors and outdoors, I came away with mixed but ultimately optimistic impressions.

First Impressions
Right out of the package, the GT Beta feels solid and dense. My unit came in around 7.8 oz with a 5.5-inch handle and 16.25 x 7.75 profile, slightly larger and longer-handled than most hybrids. The balance feels head-heavy at first, though manageable once weighted at the throat and sides. The handle seems on the thinner side. I used an overgrip on top of the original grip; it felt great for my hands/ preference.
The construction clearly reflects its beta status: small cosmetic quirks like slight edge-guard bubbling, uneven grip wrapping, or minor surface blemishes are noticeable. None of these affect play much, but they’re reminders that this version was built for feedback, not perfection.
Permagrit Surface: The Highlight
The Permagrit surface is easily the standout feature of the GT Beta, and honestly, it’s what makes this paddle worth the hype. From the very first session, I could feel how grabby the face was; it’s fine-textured but incredibly sharp in how it grips the ball. The spin potential is instantly noticeable, producing high RPMs (>2500 rpm) without needing exaggerated wrist action.
Serves jump off the face with that heavy, curling spin you can actually hear, and drives stay low and penetrating without needing to over-swing. On dinks and touch shots, the surface gives you confidence to soften the ball while still being able to roll it with spin at will; it’s that perfect mix of control and bite. Slices feel effortless; you can carve the ball and watch it skid low every single time. What really impressed me is how well the grit has held up. After hours of outdoor play, it still feels as fresh and textured as day one. Unlike most raw carbon paddles that smooth out fast, this one keeps its edge, both literally and figuratively.
Performance: Power, Feel & Control
The GT initially felt muted and underpowered. It took some adjustment to find rhythm and depth; the paddle came alive, offering better pop and drive penetration.
The overall feel is on the stiffer side. Mishits can feel harsh, and the sweet spot isn’t as forgiving as I’d like. That said, the GT rewards clean technique: centered hits feel crisp and direct, with enough stability for confident counterpunches and volleys. The soft game is workable but not effortless; drops and resets require more touch than paddles with higher dwell or flex.
What’s Next: Toward the P1
The GT Beta was built to gather feedback, and Spartus is already applying those lessons to the upcoming P1 series. Early notes suggest increased power, refined balance, and more consistent construction. If they preserve the incredible grit while improving feel and quality control, the P1 could easily become a top-tier competitor in the Gen 4 space.
Final Thoughts
The Spartus GT Beta isn’t a polished paddle; it’s a testing platform that reveals both the challenges and promise of next-generation materials. The Permagrit surface is a breakthrough, and the foundation is solid. But in its current form, it still feels like a prototype: stiff, sometimes inconsistent, and not yet tuned for every play style.
That said, I’m glad this version was released for community testing. Spartus is listening and actively improving based on real player feedback. Once the final refinements land, this line could easily evolve into something special.
Verdict: A true beta, tough around the edges but built on an innovative foundation. Exceptional grit, firm feel, and clear room for refinement. The best is still to come.
