Choosing the right driver shaft can be the difference between finding more fairways or fighting a two-way miss all season. Among the most talked-about options in today’s fitting bays are the Fujikura Ventus Black and the Mitsubishi Diamana WB. Both come from legendary shaft manufacturers, both are played on Tour, and both cater to golfers who demand stability, speed, and precision. But they are not identical. Each shaft has unique design elements that make it better suited for specific swing profiles.
In this guide, we’ll take a somewhat deep dive into both shafts, highlight the technology behind them, compare their performance characteristics, and help you decide which one deserves a place in your bag.
Fujikura Ventus Black Overview
The Fujikura Ventus Black has become one of the most iconic low-launch, low-spin shafts in the modern game. Popular among aggressive swingers and Tour professionals, the Ventus Black is engineered with Fujikura’s VeloCore Technology, a multi-material bias core construction that enhances stability throughout the swing.
VeloCore helps reduce shaft deformation at high speeds, keeping the face square longer and minimizing energy loss. The result is improved center-face contact and tighter dispersion, even under maximum load.
The Ventus Black is designed as the lowest launching, lowest spinning model in the Ventus family. It features a stiff handle, a firm midsection, and an extremely strong tip profile. Golfers with 105+ mph driver swing speeds and a desire for penetrating ball flight are the primary fit for this shaft.

Mitsubishi Diamana WB Overview
The Mitsubishi Diamana WB represents the next evolution of Mitsubishi’s legendary White Board lineage. For over a decade, White Board models have been the go-to choice for players seeking maximum stability and control at Tour-level speeds. The WB continues this legacy with modern materials and construction upgrades.
The shaft incorporates Xlink Tech Resin System, reducing excess resin for a more consistent feel and improved energy transfer. Mitsubishi also integrates its MR70 carbon fiber, one of the strongest fibers available, which increases torsional stability without adding weight.
The Diamana WB is similarly built for aggressive, high-speed swingers who want to lower launch and spin. Its handle section is firm, the midsection remains stable, and the tip section is reinforced to resist twisting on impact. Players with faster transitions and a need for ultimate control often find the WB a perfect match.

Key Similarities Between the Ventus Black and Diamana WB
Both shafts are designed with elite players in mind. They aim to keep launch down, spin reduced, and dispersion tight. Golfers who swing aggressively and tend to overpower softer shafts will benefit from either option.
Here are three core similarities:
-
Engineered for low launch and low spin to maximize distance and control.
-
Use of advanced carbon fiber materials to stabilize the shaft during the swing.
-
Preferred by high-speed players, including professionals and top amateurs.
If your swing produces excess height or spin, both of these shafts can help bring ball flight into a more penetrating window.
Key Differences: Feel and Flight Windows
While both options fall into the same performance category, their personalities are distinct. The 2024 Ventus Black has an extremely stable, almost “board-like” feel that some players love for its consistency, while others may find it harsh. By contrast, the Diamana WB provides a slightly smoother transition thanks to Mitsubishi’s resin and fiber blend.
Golfers who value feedback and a touch of smoothness may prefer the WB, while those who want unflinching stability may gravitate toward the Ventus Black. Launch windows are very close, though fittings often reveal the WB producing just a fractionally higher peak than the Ventus Black.

Fitting Considerations: Which One Fits Your Swing?
Neither of these shafts is forgiving for the wrong player. If your swing speed is below 100 mph or your tempo is smooth and moderate, you’ll likely get more benefit from mid-launch options such as the Fujikura Ventus Blue or Mitsubishi Diamana TB. But for those in the right speed and tempo range, choosing between the Black and WB comes down to finer fitting points.
Signs you may prefer the Ventus Black:
-
Extremely fast transition at the top.
-
Desire for the lowest possible spin.
-
Preference for a firmer, more stable feel throughout.
Signs you may prefer the Diamana WB:
-
Fast but smooth tempo that doesn’t need extra stiffness in the handle.
-
Desire for slightly more feel without losing control.
-
History of success with White Board shafts in the past.
On-Course Performance Testing
When tested side by side in fittings, the performance differences are measurable but subtle. Golfers with very aggressive moves often find the Ventus Black keeps dispersion tighter, particularly with misses low on the face or off the toe. The VeloCore stability shows up most when mishits are involved.
The Diamana WB, however, tends to reward players who like to feel the shaft load and unload. Its balance of strength and smoothness makes it slightly more versatile in the hands of players who want a controlled, powerful flight but don’t want to feel like they’re swinging a steel rod.
Ball speed retention is excellent with both shafts, but spin reduction may lean slightly lower in the Ventus Black. Launch, meanwhile, may sit a degree higher with the WB, which can help optimize carry for players who tend to launch too low with ultra-stiff profiles.

Professional Usage and Tour Presence
Both Fujikura and Mitsubishi have deep representation on professional tours worldwide. The Ventus Black has become a mainstay in driver setups among PGA Tour players who want ultimate control in windy conditions. It has been spotted in the bags of major winners and Ryder Cup stars.
The Diamana WB builds on a White Board tradition that dates back over 15 years. Countless Tour wins have been achieved with White Board models, and the WB ensures that players who trust Mitsubishi’s profile continue to have a cutting-edge option. While the WB is newer to the scene, its adoption has been quick among aggressive swingers.
Availability and Custom Options
Both shafts are available in a range of weights and flexes to fine-tune performance. The Ventus Black typically runs in 60g, 70g, and 80g models with flexes from stiff to extra-stiff. The Diamana WB lineup covers similar ground, with options for strong players across multiple driver and fairway setups.
To get the most out of either shaft, professional fitting is strongly recommended. Small differences in swing dynamics — transition speed, angle of attack, release point — can make one shaft clearly superior for you even if both look similar on paper.
Price and Value Considerations
At retail, both the Fujikura Ventus Black and the Mitsubishi Diamana WB occupy the premium tier. They cost more than standard aftermarket options, but they deliver Tour-level technology and performance. For golfers chasing consistency at the highest level, that investment is worthwhile.
Think of it this way: a properly fit premium shaft can save strokes every round, while an ill-fit bargain shaft can cost you fairways and approaches. The value lies in performance gains over time, especially for competitive players.
Final Thoughts: Which Shaft Should You Choose?
Both the Fujikura Ventus Black and the Mitsubishi Diamana WB are elite, Tour-proven shafts designed for the strongest players. Deciding between them comes down to feel preference and subtle performance traits.
-
If you want maximum stability, ultra-low spin, and don’t mind a firm feel, the Ventus Black remains one of the best choices in the game.
-
If you want Tour-level control with a smoother feel and slightly more versatility, the Diamana WB delivers exactly that.
Ultimately, the best move is to test both in a professional fitting environment and trust the numbers. At Tour Spin Golf, we carry both shafts and can help you find the perfect fit for your driver and fairway woods.
