A few years ago, I found this website that discusses wave characteristics and force transmission along the axis of the cue (from tip to bumper and back). I don't understand half of it, but it was a pretty interesting article.
Since it seems to be at least somewhat related to this discussion, I just had to find it. Here's the link. Enjoy.

Great read, mahalo for that, now I would like to see them run he same test with a shaft that is two inches longer then the butt. It should change the nodel point on the cue, affecting frequency points, and feedback from the cue. It would also be interesting to see where the harmonic points are on various cues, and the difference in feel when the cue is held at said points. Kinda like playing harmonics on the guitar. I understand you are not going to hold the cue at the 12th fret or centered, but if it is held on the 5th and 17th frets, kinda like one would hold a cue, there has to be some sort of different feel as these would be node points in the frequency of the cue.
Now I understand why my cue feels so dissident!
Aloha
