wood is fun, caring for it - not so much
As you do not lose anything with CF, but rather gain - lower deflection, more power, better durability and care free. And feel is something that you get used to, wood is really obsolete, just a matter of time before people would forget that cues and shafts used to be made of wood.
Maybe CF will not be the future, but definitely some sort of a composite material.
If you wish to use wood shaft, go ahead, why not? as long as you can get them, enjoy them.
I have many wooden shafts for my cues, I use them as well, but if I ever needed a new shaft, it probably won't be wood (and yes, I do have a hybrid shaft of Kielwood and carbon coming, but I don't need it, I just wanted it

)
