Deflection question, explain how a stiffer CF shaft has less deflection.

[Shooter1]

I've played with wood shafts, OEM Schon in the early days, then Mezz WXC700's and Cat and Precat Predators for the last 45 years and am fine with them. I recently tried a friends Predator CF cue and it didn't do anything for me but granted I only hit about 3 racks.
As I understand it, a CF shaft is stiffer than a comparable diameter wood shaft and would/should therefore flex less when using R or L spin and therefore push the CB off line more, creating more deflection or squirt. Am I right in this assumption?

I understand end mass has something to do with it but if CF is stiffer than a comparable diameter wood shaft and the end mass is also comparable, it seems to me that a CF shaft could actually create more deflection/squirt than a wood shaft.

I've considered buying a CF shaft before I die but would like some opinions on whether my logic above is correct.

Thanks all.

You’re not understanding it well. End mass is 99% of it. Stiffness does not matter.

There are CF shafts out there that flex more, like the SMO and Cuetec.
It is really comes down to the taper that affects the flexibility that you feel in your hand.
The front end mass is what makes the shaft to deflect more or less. I believe that the flexibility at the end of the shaft is something that tou can’t feel and can’t see without a slow motion video.

I have an InFuze keilwood shaft that is stiffer than my SMO and both perform about the same when it comes to deflection. I was quite surprised as the InFuze is quite heavy.

Do you think Carom wood shafts deflect less than Pool wood shafts?

And why or why not.

they use to be with a smaller diameter than a standard pool shaft so they had lower end mass = lower deflection (same goes for snooker cues)
Predator Z shaft deflects less than the 314, the Z has a conical taper, it is stiffer but smaller diameter and lower end mass.

'Standard' diam for a 3C shaft tip is 12mm.

I believe for Snooker tip 10-11mm.

But, Snooker 'Ferrules' are made of Brass.

I also believe the avg wood Pool shaft tip is 12.2-12.4, plus Ferrules are longer.

Deflection reduction requires a reduction IN MASS at the front-end of the cue. A stiffer shaft MIGHT deflect a lil more but it doesn't have to. Some CF shafts are both stiff and lo-defl. To get lo-def. in a wood shaft requires either smaller size/conical taper or hollowing out. Short light ferrules help also. Anything to reduce mass.

Pool shafts used to be 13-14mm
So compared to that, 12mm has much less front end mass.
3C shafts also used to have a shorter ferrule that reduces weight.

Modern pool shafts that have smaller diameter and shorter ferrule reduce the difference.

Most snooker pros these days use 8.5-9mm shafts. Most are conical taper with brass(some titanium too) ferrules. Used to be all ash cues but a lot more maple shafts are used today. A few use cf but not many.
