Project X LZ Black Onyx 6.5 Stiff+ Flex Shaft

The Project X LZ Blackout (Black Onyx) Shaft uses a .355 taper tip with a 6.5 stiffness rating. This option is best for players who want high stability and low dispersion across mid to long irons. The stiff+ profile supports aggressive tempo while preserving ball control. Choose this shaft if your swing tends toward a firmer feel and you need repeatable impact. A potential limitation is a stiffer feel that may not suit very smooth or beginner swings.
Project X LZ Black Onyx 6.0 Stiff Shaft

Designed for players seeking a balanced mid-stiff profile, the 6.0 Stiff version offers reliable launch with solid feel across a standard-length set. The .355 taper tip keeps compatibility with typical iron heads, while the upper-mid stiffness supports consistent tempo. Best for players who want predictable results without the extra stiffness of more aggressive builds. A limitation is that some swing speeds may require a different flex to maximize distance.
True Temper Elevate MPH 95 Stiff Black Onyx

This limited-edition shaft uses a .370 parallel tip with a high-launch profile. It is best for players who need extra carry and a forgiving flight, especially if they generate more speed with a moderate tempo. The Elevate MPH 95 offers a distinct look with Black Onyx branding that can complement a high-contrast set. Note that the larger parallel tip may require careful head compatibility checks on some clubs.
Project X LZ Black Onyx 6.5 Stiff+ (39.5″ 4-Iron)

For players who use longer irons or hybrids in the 4-iron range, this 39.5″ length with a 6.5 stiffness provides enhanced stability and distance control. The Black Onyx branding signals a consistent feel and predictable dispersion. Choose this if your setup relies on longer irons for a fairway approach, but be cautious if your current swing speed is on the lower end—this shaft leans stiffer and may feel firmer to slower swingers.
Project X LZ Black Onyx 5.5 Regular+ (36.5″ Wedge)

The 5.5 Regular+ flex is suited to players who favor a smoother feel and moderate swing speeds. The 36.5″ length on a wedge makes it a practical choice for players seeking more precise control around the greens without sacrificing too much feel. Best for players prioritizing touch and shot-shaping with shorter irons or wedges. A limitation is that Regular+ can feel softer for aggressive swingers who prefer extra stiffness.
Generic True Temper Dynamic Gold 105 S300 Black Onyx

This option combines the familiar Dynamic Gold profile with a Black Onyx edition and a .355 taper tip. It features a mid-low launch/spin balance aimed at players who desire reliability across a full iron set. Best for players seeking a versatile shaft with predictable performance in a standard mid-length configuration. A possible drawback is that it may not deliver the slightly higher launch that some players prefer in gainful wind or longer courses.
Buying Guide
What flex should you choose for black Onyx steel shafts?
Flex choices range from Stiff to Regular+ and S300. In general, stiffer options suit faster swing speeds and players who want tighter dispersion, while regular or mid-flex options support smoother tempos and increased comfort. Always match flex to your typical swing speed and tempo to balance distance and accuracy.
Is the .355 taper tip compatible with most iron sets?
Yes. The .355 taper tip is a common standard for many steel irons. It ensures compatibility with a wide range of clubheads. If your set uses a different tip, you’ll need adapters or new shafts. Verify tip size before purchasing to avoid installation issues.
How do length options affect performance?
Longer shafts can increase swing speed and distance but may reduce control. Shorter shafts improve accuracy but can lower distance. Choose a length that matches your current clubs or seek a custom fitting that optimizes swing weight and balance for your posture and stance.
What should buyers know about Black Onyx branding?
Black Onyx branding emphasizes a uniform look and feel across shafts. While branding does not dictate performance, it helps players maintain a consistent aesthetic across a set. Ensure the shaft’s stiffness and length align with your playing style, regardless of branding.
How to pick the right shaft for wedge to long iron gaps?
Wedges typically benefit from lighter, smoother flexes to enhance touch. For longer irons, stiffer options can provide more stability at speed. Consider using a wedge-specific shaft with a shorter length and a regressed torque to maximize control in short-game shots.
FAQ
- Q: Do Black Onyx shafts affect ball flight the same across different brands?
A: Each shaft model can influence launch and spin differently; consult a fitting to find the right balance for your swing. - Q: Are these shafts suitable for beginners?
A: Some offerings, like Regular+ and mid-flex options, can be beginner-friendly, but a fitting helps determine the best starting point. - Q: Can I mix shaft brands within a single set?
A: Yes, but mixing brands requires careful fitting to maintain consistent feel and performance across clubs. - Q: What is the advantage of a .370 parallel tip versus .355 taper tip?
A: A .370 tip tends to offer a different seating depth and potentially a slightly different feel and launch profile; verify compatibility with your irons. - Q: Should I replace all shafts at once or incrementally?
A: A full set replacement provides uniform feel, but incremental upgrades can manage budget and test impact gradually. - Q: How important is a professional fitting for shaft selection?
A: Very important. A fitting accounts for swing speed, tempo, and iron length to optimize dispersion and distance.
