Speaking of tonal woods and cues. I have a cue that Dave Kikel made of camatillo. I had him ship me all the camatillo he had in his shop. I received it and there were four pieces of straight grain black and violet colored pieces. The tonal sound was unbelievable, a rich deep enchanting sound. I went around for two days tapping them and listening to the tone and the length of time you could hear it. Really quite an experience. I chose the straight grain black and violet pieces labeled what I wanted and shipped it all back. Dave and I finally agreed to build it with all ivory points(4 hi 4 lo) in the forearm and the butt, rings, joint, butt cap, ferrules and joint protectors all ivory. It is stunning to say the least, Dave's sister was in love with it according to Dave!
Cue vibrates like a tuning fork.

What does knowing the grain orientation do? How does it provide useful information to the shooter?
Whoa. I just saw this. Let's be clear here. Most people think of deflection in terms of cb squirt only, but there is also shaft deflection. Speaking about solid wood shafts only: The stiffer the shaft, the less shaft deflection on impact, but that results in greater cb squirt when side spin is applied as opposed to a flexible shaft.
Yes, but according to Dr. Dave not a significant increase within the normal range of pool/billiards shafts.

The shaft, having a spline will always flex in one direction easier that another direction.
That is one of the things segmented and carbon fiber shafts try to eliminate.
Bob felt that having the shaft deflect in the same direction for every shot would help with consistency.
Whether or not that actually helps the player, and to what degree, has been debated.
How was it intended to be used? I'd guess for maximum consistency the spline would always be rotated toward the CB's center.

I guess it depends what shafts you're comparing. I went from a Meucci to a Schuler constant taper. That's like going from a tuning fork to a block of wood. Besides, how do you dispute the feedback a player gets and the adjustments they have to make with all other things being the same? I've been saying this all along --- these scientific studies may be helpful, of course, but they're not necessarily absolute. There are a lot of variables that aren't factored into these tests they do.Yes, but according to Dr. Dave not a significant increase within the normal range of pool/billiards shafts.

You used the cue with the colored dot facing up.
That way every shot had the shaft in the same position relative to the spline.
Whatever deflection or bending the shaft did when it struck the cue ball it did it in the same direction every shot.
Thanks for the info.
Thanks.
But it seems to me that hitting with straight follow or draw would push the shaft up or down in line with the spline, while hitting with straight sidespin would push the shaft sideways 90 degrees from the spline, and other tip placements would push the shaft other directions relative to the spline.

True ... the force acting on the shaft from striking the cue ball will act as you say.
However ... the spline of the shaft will flex easier in only one direction and will resist flexing in any other.
With the spline in a random alignment the resistance to the flex will be lesser or greater thus the actual flex will be lesser or greater.
With the spline always in the same alignment you get the same flex every time you make the same stroke.
Consistency and the brain's ability to learn from the results is what it is all about.
The new carbon fiber shafts reduce the spline and its effect on shaft flexing to almost zero.
It can be tested and verified in lab type tests.
Does this actually make a difference to the pool player?
Are we over engineering something that has a very small effect on real play?
I have an early Cynergy 15k shaft that I ordered from Seyberts with a Kamui Black medium tip and Radial joint. The butt is custom, made of Kingwood. I have never noticed any sort of tuning fork type of vibration out of it since I first got it or now that I am using Moori medium tips.
Before I bought it I tried the early Predator CF shaft that a team mate had bought and immediately noticed a ping sound/vibration when I shot with it. It doesn't bother him but it bothered me enough within 6 shots or so that I went with the Cynergy.
I am a musician so maybe I'm more sensitive to such things but am quite happy with the Cynergy in this and all other regards. Based on my experience your issue may have something to do with the joint and/or the materials used in the butt, assuming there is no difference (besides the joint type) between my shaft and yours. My friend (now retired) preferred the Radial joint and made it as a wobble fit so that the faces on the butt and the shaft would seat precisely, making it feel like one solid piece, to the extent possible.
