Project X HZRDUS Smoke Black Shaft Review

50 Words or Less

The Project X HZRDUS Smoke Black shaft is the next generation of low launching, stout HZRDUS shafts.  Very low spin.  Extremely stiff profile.


Project X’s HZRDUS line, first introduced in 2015, became an immediate hit on Tour and among gear enthusiasts for its ability to drop spin and stand up to aggressive swings.  The HZRDUS Smoke Black is the second generation of HZRDUS, using new material placement and a tweaked design to deliver that same consistent performance with better feel.


The HZRDUS Smoke Black looks very similar to its predecessor but with some notable changes.  The hazmat placard is still the most eye-catching part of the design, showing the shaft’s weight, torque, flex, and spin characteristics.  What’s new is the base color – charcoal grey instead of matte black – and the bolder “HZRDUS” graphic.  If you’d prefer all that out of sight, you can flip it logo down for a completely clean look at address.

Also worth noting: you won’t see the “Handcrafted” graphic on any HZRDUS Smoke Black shafts.  Project X states that there are no differences – aesthetic or otherwise – between their aftermarket and stock shafts.


The biggest difference between the HZRDUS Smoke Black and the original HZRDUS Black is that the torque is higher in the Smoke.  This gives the Smoke a smoother feel than the original despite the fact that Project X actually made it stiffer along the length of the shaft.

If you’re looking for a shaft to provide some kick, look elsewhere.  However, if you want a shaft that’s going to stand rock solid against your most aggressive swings, the HZRDUS Smoke Black is right up your alley.


I’ve had the opportunity to test the HZRDUS Smoke Black in a few different driver heads, and it does the same thing in every one: produce low launching, low spinning bullets.  Because of my positive angle of attack, I’m used to seeing my drives launch in a fairly high window.  With the HZRDUS Smoke, that window was noticeably lower, and the ball flight was as flat as can be.  For me, this combination brought me out of the optimal range, but for a high spin player it could result in huge distance gains.

Similar to the original HZRDUS Black, the Smoke Black took all the surprise out of my shot shapes.  Good swings produced arrow-straight shots.  Bad swings gave me the exact results I expected, too, be they a pull or weak push.  With so little kick, this shafts gives back exactly what you put in.

The change in feel from the original HZRDUS Black did make a noticeable performance difference for me.  With the original, I felt like I wanted to go 100% all the time.  The smoother HZRDUS Smoke Black let me make that 80%, “fairway finder” swing more confidently.


If you found the original HZRDUS Black too harsh or demanding, do yourself a favor and check out the second generation HZRDUS Smoke Black.  Project X has done a great job of maintaining the performance characteristics of the original while making it feel much smoother.

  1. I notice your clubhead speed is 103 vs 108 with the Diamana DF. Is it because of this Hzrdus Shaft? How does the Smoke shaft compare to the Hzrdus Red?

  2. Frank Benson

    Upgraded to the new Callaway Epic Flash with the HZRDUS Regular shaft. Looking forward to see how it performs.

  3. How would you compare the Smoke Black to the Evenflow Black. They are both described as low/low shafts that have better feel than the original Hzrdus Black.

  4. David Patton

    Hey Matt,

    I read your review of the EvenFlow Black, but your description of both shafts are very similar. I was wondering whether that is accurate or whether there are differences in feel, liveliness, stability, or other characteristics. Thanks!

  5. My epic flash with a Hzrdus Smoke shaft had the head cracked. They sent me a replacement with the Project X Evenflow shaft. How would you compare the two?

  6. Hi Matt-

    Definitely enjoy your reviews. Did you happen to frequency test these at all? I remember the original Hzrdus played a full flex stiffer than stated. Curious about this. If you’re a 6.5 player, do you get 6.0 or are the smokes more true to stated frequency?


    • Matt Saternus


      No, I do not frequency test shafts.



      • Hello Matt, as a 15 handicap which hzrdus shaft would u recommend for myself, I have a tendency to push the ball a little right and what seems to be a fairly high ball flight. Thanks Marty

        • Matt Saternus


          Picking a shaft doesn’t have much to do with handicap, it connects with swing speed, transition, feel preferences, etc. If you want to find a shaft that improves your game, you need to work with a qualified fitter like Club Champion.



  7. Chris Greenway

    Hi Matt, just as a rough guide, which hzrdus smoke flex would a 105 mph swing speed support please? I was going 6.0 but think it might even be 5.5. Thanks again.

  8. Alexander Kubala

    Just wondering if you could compare the new Hzrdus Smoke Black to an Atmos Black
    Thank you

  9. John Robertson

    Thanks for the review Matt! I recently bought a Titleist TS4 with the HZRDUS Smoke Black (6.5). I like it, but I have a little buyers remorse that I did not go with the 6.0. My driver speed is 99 mph, do you think it would be a worthwhile experiment to buy a 6.0 and the Titleist adapter to compare? The $150 wouldn’t bother me, but no point wasting the money if you think the 6.5 is an obviously better choice.

    • Matt Saternus


      On the whole, I think most players at 99 MPH would be better at 6.0 than 6.5 in this shaft.



  10. Matt,
    Currently gaming a Smoke Black 6.0 70g in my drive with a swing speed around 105 faster tempo and load but smooth swing style 2 handicap player. The answer is undoubtedly go get fit to dial in this level of detail, but I’m wondering if in your opinion moving to a HC Black or Yellow OG HZRDUS at 62g to try and atttain more club head sped while potentially upping the flex (or tipping) to maintain dispersin and spin characteristics of the 70g wouod be a worthwhile adventure? Looking to go lighter without losing the feel of the Smoke Black.

    • Matt Saternus


      You got it: go get fit.
      If the journey is the destination and you want to fart around with your gear, by all means try the experiment, but if you just want to play better now, let the professionals do their job.



  11. What swing speed would you recommend for the 6.5 hazardous smoke black? Thanks.

    • Matt Saternus

      With the caveat that swing speed is not the be-all-end-all metric for fitting a shaft, I would think you’d want to be north of 105 MPH.


  12. I read your review of the Evenflow black as well. Compared to the smoke do you remember which you would prefer? I have hit both of them with similar numbers and can’t decide between the two. Thanks for your reviews!

  13. Just got fitted for this shaft in conjunction with a TaylorMade M3 460cc head (at a good price since it’s not the “latest and greatest” M-line driver anymore, too). Everything felt connected with that combo– other shafts felt like a driver head with a shaft connected to it with a human connected to it… if that makes sense. Like there were 3 distinct entities in the swing. Everything felt very linear and and together with this shaft when I swung. Got some distances that I didn’t think I was capable of reaching, and without swinging out of my shoes. Tighter dispersion than other combos too. I’m pumped.

  14. Hey Matt — Looking for comparable alternatives to this shaft. Typical swing speed is about 110. Options to consider?

  15. Hello Matt, love these short sharp reviews. Could you suggest which out of black or smoke black would “feel” closest to a Diamana D+ 70 X. Spec wise I know the Black in a 6.5 with a torque of 2.9 is closest but sounds like it would have a more harsh / boardy feel than the D+. Just trying to find a cheaper replacement for a broken fairway shaft than the D+ (which I completely loved).

    • Matt Saternus


      In my opinion, the Smoke Black is smoother feeling than the original Black and thus a closer comparison to the D+.



  16. I was just fit for SIM Max in both driver and fairway. Interestingly enough, I ended up with Hzrdus Green in 6.5 for the driver and Smoke Black in 6.0 for 3 wood both in 70g with a swing speed between 100-105 for driver. This goes against “conventional wisdom” but this is a classic example of how important it is to get fit. 6.5 in the fairway wood wasn’t producing the height I’d need so we dialed it back a touch and it was bang on.

  17. Brian bell

    Hey Matt, love your reviews. Currently playing the smoke black 70g 6.0 flex in driver and 3 wood. Best shaft I’ve used! Is there a steel iron shaft that would be comparable to this? Currently playing kbs tour 6.0.
    Thanks, brian

    • Matt Saternus


      If you like the Smoke Black, I would guess you want an iron shaft with little to no “action.” I would suggest trying Project X or Dynamic Gold.
