I agree with the shaft being a major contributor to the playing uniqueness of the cue. However, over the years I have began to think that the butt has more to do with it than
we had given it credit for in the past. With all due respect being given to the shaft the butt plays a significant part in the equation. When your trying to get that last 5, 10 or 15%
more of performance out of the cue there is not much "tweaking: left to be done with the shaft but the butt opens up a whole new frontier with wood combinations, pin materials,
joint materials and construction methods. Just my thoughts on the subject,
I played around with it several years ago with bamboo shafts but when you get down to 13mm it looses its stiffness and gets to whippy. In order to get the most out of it it needs to be in compression. That is trapped between a solid forearm and a threaded but cap and sleeve. People like it for a handle sleeve when coupled with BRW, BKW, PH and Walnut which it what I have used it with. I might try it with a cored forearm/butt sleeve in the future.
