Ryan I do not think that the length of the pin will change much if anything. To my understanding when the tip hits the cue ball the vibration we call hit begins, it then moves at the speed of sound to the butt cap and then back to the cue tip, this movement is what we perceive as a cues hit. If at anytime this vibration is interrupted the vibration will be interrupted, the pitch of the vibration and the sound will be changed from bell like to a cracked or broken sound. This is why in most cases if something is loose on a cue it will sound like the difference in tone is coming from the cues tip or ferrule.
In my opinion so long as all parts of the cue are securely joined (Nothing is loose) the tone of the cues hit will not be changed by a long or short metal doweled screw at the A-joint.

Craig,
I agree, but also disagree.
You are correct that the "sound waves" created by the hit travel up and down the cue at the speed of sound through that material.
However, I don't refer to those sound waves as what we call "hit". These sound waves are completely linear and they travel up and down the cue with no physical movement of the cue. They are also at a relatively high frequency. I don't believe that we can feel these waves, only hear them.
Also, when we hit the ball off center, the cue bends creating a physical wave or bending motion that travels down the cue. This is what we "feel", the side to side shaking of the cue in our hand. This "physical wave" is a much lower frequency than the "sound wave" and we can very easily detect it as well as small changes in the frequency or amplitude.
Obviously, most of us combine what we feel and what we hear into one thing, even though they are completely different.[/QUOTE]
Thanks for your perspective, and since you have broken it down the way you have done I totally agree with your view. I think I was trying say something similar to what you have said just not as clearly.
Thanks for the correction.
