Man, those are some ugly cues too!
I have to imagine in time the shaft will be offered on more cues and eventually separately. I'm highly intrigued by the shaft. Working in an industry that makes extensive use of carbon fiber (cycling) and for one of the few companies who do their own carbon fiber manufacturing in the US, I'm very familiar with the material and how advantageous it can be in certain implementations. I don't know that we'll see the day when carbon replaces wood in cues, but that was once said about bike frames and carbon has done just that, so I also wouldn't put it out of the question.
Would love to get my hands on one of these shafts to try out someday and see how it performs.
Also, the appeal of a shaft that won't warp if you leave it in your car regardless of the season is kind of appealing too.
