Before the 'new' fangled LD shafts a flexible shaft was a means of cutting done on the CB Deflection. Bob Meucci was probably the first or one or the first cue makers to extend the parallel taper well up toward the joint. That creates a vibrating shaft. Since I learned with conical taper house cues that were stiff, I hated the vibration.
Now as Ms. Crimi implied, one can get the Low Deflection with a more stiff shaft. Problem solved.
No it creates a Ducking low frequency cue, this moves the nodal points closer to the joint which makes each end of the cue undergo the highest amount of movement crests and troughs of the lateral wave and a slower longitudinal wave (compression) that propagates during impact.
Bob never spearheaded claims that straight Long pro taper was done and was intended to reduce Cue ball Squirt (what your calling deflection)
His taper was made for no reason and intention more than it felt more comfortable through the fingers especially for lower skilled players, and marketed that the parallel pro taper delivered the tip more accurately than a traditional taper that would make the tip rise its position as the shaft diameter increased. Even tho because a cue pivots in our grip and bridge any raise at the bridge sees an proportionate drop of the tip…..AFTER the ball is long gone a elbow drop and long follow through will have the tip raising in relation to the taper diameter growth.
Truth that it happens but a flat lie that it applies to accurate placement of the tip on the ball. It’s bullshit.
He used long ferrules that increased end mass, created higher CB squirt/deflection despite the shaft having a noodle for a spine as more flexibility is not the impetus of a low amount of squirt on cb.
The CB squirting out like a slippery bar of soap merely gave the illusion that more English and spin was being created. When because of the design more English was necessary to effectively combat the squirting cb, and resulting in more swerve occurring.
Same tip sizes same radius and speed and angle of acceleration and angle of velocity between any cue ever made…produces the same quantity of English and spin.
LD cues don’t jump and masse well because a low squirting CB makes it harder to attain high swerve. So instead of a masse being a gradual curve hooking, the cb will go sorta straight and then jerk off it to a new mostly straight vector….it becomes more a skid then rolls.
So now that we have those fables covered we can address the vibration.
It’s not the vibration you dislike it’s the large deformation of the cue overall….IT DUCKS AND CANT DO ANYTHING BUT DUCK. Thats how DPK would describe that.
Low deformation from nodes being close to around a 10” ish from the tip and buttcap make a tighter higher frequency and more resonate feel to the cue. It becomes more harmonious. It doesn’t Duck and fold in half during impact.
Bobs cues distinctly lack harmonics…harmonics do not just mean vibration to be clear .
Smaller tips and ferrules shafts were around long before fat 13s and ferrules as the standard we know. So technically LD existed first. Ivory and buckhorn ferrules came secondly, then black plastic then finally white plastic.
