An AZer told me this:
I got SMO shaft and if you care just about the deflection this shaft is REALLY good in this regards. On the other hand the shaft is considerably lighter (0.3-0.4oz) than what other CF shafts usually weight so it messes to certain extent with the balance of the cue, also the feedback is not all that pleasant and full though its not REVO-level of unpleasantness but still it is something to consider.
FYI there are several grades of cf threads with different properties and of course different prices. Also there are literally hundreds of ways how the thread is woven into a shape of shaft so the reasearch and development can be VERY expensive if you want to create a really great product. Hence the price difference between the shafts JFlowers offers, their cheaper shafts have considerably higher deflection.

--- There’s a weight bolt inside the shaft but it can’t be adjusted as Jflower don’t supply different weight bolts for this adjustment.
--- It is the only shaft so far with a weight bolt so of course I used it and the adjustments can make it feel like a totally different cue. Best bang for the buck!
--- I like this shaft a lot, probably as much as my 12.9 Revo – it plays very similar to my Predator 12.9 revo. The deflection tests i performed with the SMO were surprisingly good even on a 10 foot table. I also like the tip that came on the SMO shaft thou I use a soft tip normally. Great job on a great product – the carbon fiber is not as clean as the predator shaft but a person needs a magnifying glass to look closely – Stay tuned for our positive review of this shaft on the return of SNAP Magazine returning in July 2025. Excellent Product – far superior to any of the cheaper CF shafts such as Raven, Bull and others. I see you now make a 11.8 diameter shaft, I will be ordering one of those SMO shafts soon for testing. I will be using my new SMO in competition and using my Revolution as my back up.
--- I bought this shaft after hearing about its low deflection assumed best in the market. I tried and seems it’s true and at last equal to predator revo 12.4 that I used before. Taper is different because SMO is pro taper (cilindrical in the foremost part) and revo not (it’s conical) but i think pro taper it’s more comfortable.
---J Just AMAZING Shaft and a very big step forward for any player who using normal low deflection shafts , its really very low deflection , Balanced, steady , great power and high responsiveness ,very soft and nicely slimmed down to the Tip like LADY , plus the gorgeous silver hoops in the white ferrule & collar. I just wish if they work on improving the sound but it’s fine no annoying sounds,
--- Ordered two SMO shafts and one started losing the black ringwork right below the ferrule after a couple nights of play (I’m sure it was a simple material flaw). Messaged JFlowers and they sent me a new one now questions asked. Awesome customer service and absolutely no issues with the other two shafts. They play great and I love the long taper. Definitely a competitor to my teammates revo, cynergy and defy. I prefer my SMO, especially at its price point
--- I have used the SMO shaft for a while now and it’s my go-to shaft. My backup is a 12.4 revo. Both shafts are very low deflection, but the SMO has a taper (long protaper) that suits me better. I have mixed feelings about the Fusion tip. In some instances, it feels stiffer (harder) than others. But it always seems to work and hasn’t let me down.
--- Amazing preformance, extremly low deflection, nice low pitch sound, not stiff and a nice looking shaft with a thic white ferrule and the silver inlay work is fantastic!
