I think this thread is going in the wrong direction. I do not believe that a heavier shaft is made by altering the taper whereby leaving more wood on the shaft to make a heavier shaft. A heavier (or denser) shaft is made by choosing a different piece of wood which will yield a heavier shaft; not by altering your taper. And, in my opinion, any cue maker who alters his taper to make or deceive the customer into thinking that they now have a heavier shaft is the wrong way to do business.
Let me explain: every cue maker, supposedly, has their own specific taper. What we are talking about here is using that very same 'specific taper' on every shaft BUT, you choose a heavier piece of shaft wood with your standard taper to yield the heavier shaft. You don't alter the taper and make a heavier shaft; you use a denser piece of shaft wood to yield a heavier shaft.
And, to the baby kangaroo out there; in my opinion which is based on actually seeing, hearing and showing and then showing again by using thousands of shafts - the tonal quality or "tap tone" of wood cannot be judged by the ear alone with any sort of consistency. I don't and won't go into how and why but after seeing and hearing this taping in person, our ears cannot differentiate the tonal quality with consistency. And, I can prove this in person to anyone who wants to doubt this statement. In fact, choosing shafts by tonal quality or 'tap tone' is an exercise in futility because given the opportunity to choose from thousands of shafts, then come back and choose again, you WILL choose shafts that were previously rejected.
Here's the bottom line: The cue maker can produce just about anything that the customer wants whether it's right or wrong. Many cue makers will prostitute themselves for just about any idea in order to sell a cue. With all the hype about various laminated shafts, I'm more and more convinced that if someone had enough money they could start a business by promoting and selling impregnated balsa wood as the next best and greatest new shaft design. Just take a look around today and see all the different methods of manufacturing new designs. The best and most complicated design, hands down, goes to the OB shaft design. I don't know if it plays better but anything that complicated has to be better; right!?
Meanwhile, back to the impregnated balsa wood shafts. The manufacturer could get some pros to play with their product and pay for all the charts and comparisions. While the impregnated balsa wood is a ridiculous idea, the fact remains that given sufficient resources, anyone can promote the next best widget in this business and the players will flock to the stores to purchase them. Why? Because we're in the instant gratification generation and time zone where money can solve all problems (or so they think) rather than hard work and practice.
