Technical Analysis — Pickleball.bz · June 2026
A science-first teardown of Spartus PermaGrit™, Honolulu Crystal Blue™, and 11six24 HexGrit™ — comparing core architecture, surface engineering, and what the physics actually mean for your spin ceiling, volley speed, and long-term performance.
Context
For three years, the arms race in pickleball paddle engineering focused almost exclusively on the core: honeycomb gave way to thermoformed polymer, which gave way to Gen 4 floating foam. Players celebrated. Then they noticed their $200 paddles going smooth in three months.
The problem is fundamental to how raw carbon fiber surfaces work. Peel-ply texture — the sandpaper-like roughness that gives paddles spin potential — is a surface-level phenomenon. Friction against balls, court surfaces, bags, and other paddles mechanically abrades it away. By the 30–50 hour mark of heavy use, most raw carbon paddles lose a measurable fraction of their grit, and with it, their spin ceiling.
In Q1–Q2 2026, three engineering teams arrived at the same problem from different directions. Spartus, assembling in the USA, launched the P1 Hybrid with PermaGrit™. Honolulu Pickleball extended their Crystal Blue™ J-Series. 11six24's Power 2 posted the strongest independent lab numbers to date behind HexGrit™. This article breaks down what's actually happening at the molecular and structural level — and what it means on court.
Core Engineering
All three paddles use variants of Gen 4 floating foam construction — a significant departure from the polymer honeycomb that defined Gen 3. To understand why the architectures differ, you need to understand what EPP and EVA actually do under impact.
Expanded polypropylene (EPP) is a closed-cell bead foam — roughly 95% air by volume, with millions of fused polypropylene spheres each acting as a micro air-cushion. When a ball strikes an EPP core, impact energy distributes across millions of particle boundaries rather than being returned elastically. This means EPP absorbs and redistributes energy, producing the characteristic soft, "plush" feel and extended dwell time that foam paddles are known for.
Longer dwell time has a direct mechanical benefit: the ball stays in contact with the face longer, giving surface friction more time to act and generating higher RPMs at equivalent swing speeds. EPP also eliminates the core-crush failure mode endemic to polymer honeycomb, where repeated impacts permanently deform cell walls.
Ethylene-vinyl acetate (EVA) foam behaves differently. Its polymer matrix is more uniform, returning energy more quickly and elastically — producing more "pop" and a livelier ball departure. EVA's higher elasticity raises ball exit speed slightly, but at the cost of reduced dwell time. The trade-off is measurable but smaller than feel suggests: independent testing of EPP vs. EVA elongated paddles at identical specs showed only a 0.2 mph serve speed difference — statistically within measurement noise.
The real reason modern paddles combine EPP and EVA is zonal response: EPP at the center captures the soft game (dinks, resets, drops), while EVA at the perimeter contributes stability, twist resistance, and pop on off-center strikes. Where brands differ is in how they engineer the interface between these materials.
Fig. 1 — Core Architecture Cross-Sections (Schematic)
Spartus makes no exotic structural claims for the P1's core — instead betting on materials well-executed: Gen 4 Dual-Density Floating Foam, where EPP and EVA are graded in density across zones rather than a simple two-material float. A denser EPP center captures soft-game dwell and precision, while a progressively springier EVA perimeter provides pop and twist resistance on off-center drives. No tenon joint, no control joint — the construction's case is that good foam engineering at the material level makes structural gimmicks unnecessary.
The face is a noteworthy hybrid: Toray T700 carbon fiber combined with fiberglass rather than pure carbon. T700 is a high-tensile-modulus intermediate fiber — stiff, responsive, efficient at energy transfer. The fiberglass blend softens the pure-carbon harshness, gives the face a distinct tactile character, and may interact differently with PermaGrit's crystalline bonding process than a monomaterial carbon substrate would.
Honolulu's Control Joint™ Technology introduces a deliberate flex zone — a structural discontinuity across the paddle face that allows controlled bending during ball contact. The floating-pivoting core means the EPP is not rigidly bonded to the frame, reducing vibration transmission to the handle and allowing the core to move slightly relative to the face. Their marketing claim is more power with more control, which is normally a physical trade-off. The mechanism: the pivot allows dwell time to extend on soft shots (the core compresses more freely) while the elastic perimeter snaps back quickly on hard shots.
The Power 2 makes fewer architectural claims. It uses a Gen 4 floating foam construction — EPP center, EVA perimeter — without a named structural joint innovation. The bet is that good materials, well-executed, plus an industry-leading surface technology, are sufficient. The data so far supports this: 2,335 RPM spin rates and 98% grit retention don't require a novel joint architecture if your surface is engineered correctly.
Surface Engineering
The three grit technologies represent three distinct engineering philosophies for solving the same problem: how do you bond abrasive texture to a carbon fiber composite face such that sustained ball friction won't remove it?
Fig. 2 — Grit Surface Architecture (Microscopic Cross-Section Schematic)
Spartus describes PermaGrit as a "crystalline finish" that "sparkles in sunlight" — unusual marketing language for a grit surface, but language that suggests the texture is a structural feature of the material rather than a deposited coating. The independent testing results are the most striking in the field: Pickleball Studio reported "0% degradation" over 80 games, calling it "by far the best grit we have seen." A second source, Pickleball Effect, confirmed "PermaGrit is legit" without caveats.
Two independent validators citing zero degradation is meaningfully different from a manufacturer claim. The precise mechanism isn't published in the same engineering detail as Honolulu's firearms-heritage approach or 11six24's polymer-matrix method — but in paddle equipment, published test data has historically been more predictive of real-world durability than engineering rationale alone. The hybrid CF/fiberglass face may achieve a bonding geometry unavailable on pure-carbon substrates: crystalline structures may lock differently into a composite matrix than into monomaterial carbon.
The manufacturer claims 2,100+ RPM spin — comparable to the 11six24 Power 2's published figures. Given the surface durability data, the spin retention trajectory over time is more directly interesting than the launch number.
Honolulu's approach is explicitly physical rather than chemical. The Crystal Blue™ process uses "precision crystal-infused particulate encapsulation" — crystal media particles are mechanically interlocked into the carbon fiber face during manufacturing. The company draws on heritage from the firearms industry, where mechanically interlocked abrasive surfaces must maintain grip under sustained mechanical punishment over thousands of cycles.
Mechanical interlocking is well-understood engineering: particles lodged in a substrate cannot be removed without fracturing the substrate itself. The failure mode shifts from "particles wear off" to "particles fracture in place" — a much longer degradation timeline. Independent grit-wear tests have confirmed Crystal Blue as one of the few paddle surfaces holding texture meaningfully past the 30–50 hour cliff where standard peel-ply fails.
11six24's HexGrit uses "embedded fine particles that behave entirely differently from traditional peel-ply" — particles integrated into a polymer matrix layer on the carbon face rather than sprayed on top. This is conceptually similar to Crystal Blue but with a different embedding process and particle geometry. The "hex" name suggests hexagonally-arranged micro-particles optimized for multi-directional friction.
HexGrit has the strongest published performance data of the three: 98% grit retention after 100+ hours in accelerated wear testing, 8.9% spin degradation vs. competitors losing at nearly double that rate, and 2,335 RPM — 4th highest ever recorded across 440+ paddles in independent lab testing.
Physics & Performance
Serve speed is primarily determined by swing speed, paddle mass distribution (swing weight), and the coefficient of restitution (CoR) at the paddle face. Gen 4 foam cores do not inherently increase ball speed — EPP actually absorbs and redistributes some impact energy rather than returning it. The real serve-speed benefit of foam construction comes from the expanded sweet spot: a ball hit slightly off-center on an EPP core loses far less speed than the same contact on a polymer honeycomb, because the EPP's closed-cell structure distributes the load across a broader area.
All three paddles use the same fundamental foam construction, so serve speed differences between them are driven primarily by shape (swing weight) and face stiffness. The Spartus P1's hybrid face (T700 CF + fiberglass) may produce a marginally softer ball departure than a pure-carbon face — consistent with the dual-density foam philosophy of exchanging peak CoR for broader forgiveness.
Fig. 3 — Ball-Paddle Dwell Time and Energy Transfer (Conceptual)
At the net, where players are sometimes 14 feet apart and a 45 mph ball gives only 0.2 seconds to react, volley speed is a function of swing weight, hand speed, and stiffness of the paddle-ball interface. A stiffer face means less energy is lost to face deformation during the brief contact window — more energy goes back into the ball.
EPP foam cores are inherently less stiff than thermoformed polymer — this is part of why foam paddles have lower peak CoR numbers than Gen 3 paddles on drives. However, for volleys, the shorter swing arc and the importance of control mean the soft feel of foam is often preferred. All three paddles share similar stiffness profiles; the Spartus P1's fiberglass-blended face may produce the softest touch of the three on delicate resets, while the Honolulu's Control Joint delivers the widest dwell envelope on punch volleys.
This is where the durable grit technologies most directly separate themselves from standard carbon paddles — and from each other over time. At launch, all three will likely perform similarly, with the COF-maximizing texture providing high friction during the contact window. The divergence happens at the 30–50 hour mark.
Fig. 4 — Spin Retention Over Time: Published / Independent Test Curves
For the average competitive player logging 5–10 hours per week, the pre-2026 raw carbon cycle looked like this: excellent performance for 4–8 weeks, noticeable grit degradation at 8–12 weeks, and a paddle that felt dead at 4–6 months. At $180–$250 per paddle, that's an expensive upgrade cycle.
PermaGrit's "0% degradation over 80 games" is the most striking single durability figure in this comparison — though "game" and "lab-hour" aren't directly comparable without knowing average game duration and intensity. HexGrit's 98% at 100+ hours comes from accelerated wear testing; PermaGrit's 0% figure comes from Pickleball Studio's game-count methodology. Both validate long life; direct apples-to-apples comparison requires the same protocol applied to both surfaces simultaneously.
Crystal Blue's independent grit-wear tests place it in a similar tier — verified past the 30–50 hour cliff with strong community track record across multiple sold-out production batches. The structural core question for all three is whether EPP-EVA interface bonding holds cohesively after thousands of high-speed impacts — the foam construction eliminates core-crush, but bonding quality determines long-term performance.

Bottom Line
All three paddles represent the frontier of durable-grit engineering. The differences are meaningful but not large — and the gap between any of them and a standard raw carbon paddle is larger than the gap between them. Here's where each earns its place:
Spartus P1 Hybrid
BUY IF
...you want verified durability and in-stock availability
PermaGrit has the most striking durability claim: "0% degradation" over 80 games per Pickleball Studio, with independent confirmation from Pickleball Effect. Two validators without caveats is the highest confidence signal in this comparison. The hybrid T700 CF + fiberglass face is a genuine material differentiator, and USA assembly adds build quality reassurance. At $219.99 — including a free neoprene cover — it ships now with no pre-order risk. Single-SKU hybrid shape limits options compared to competitors; elongated-shape players should look elsewhere at launch.
Honolulu Blue Grit
BUY IF
...you want verified grit longevity + shape options
Crystal Blue™ has the strongest narrative backing — independent grit-wear tests, the firearms-industry heritage story, and multiple sold-out batches suggest real demand. The J6CR elongated gives power players reach and swing weight options neither P1 nor Power 2 offers at launch. The Control Joint flex-zone is a real architectural feature. Pre-order risk is low given demonstrated demand and batch fulfillment history. Best for elongated-shape players who want verified grit performance without paying a premium for USA assembly.
11six24 Power 2
BUY IF
...you want the strongest published independent data today
HexGrit has the best independently published numbers: 98% grit retention at 100+ hours, 2,335 RPM spin (4th all-time), 8.9% spin degradation. The paddle ships same-day with no pre-order wait. Three shape options means you can match play style. For data-driven buyers who trust lab protocols over game-count methodology, HexGrit's testing approach is more controlled. At $209, it splits the price difference between the Spartus and Honolulu offerings.
