Well I stopped and I thunk. A hall of fame cuemaker suggested an ash shaft for the 2 reasons I mentioned. Guess I better think again.
Hard for me to disagree with a hall of fame cue builder but think how many other hall of fame cue builders prefer maple. One other advantage of ash is that quality ash is easier to come by, might be why the builder tried to push ash.
They mostly use maple for baseball bats with some ash being used. Under the demands a pro ball player puts on a bat the cell walls of an ash bat break down and the bat goes flat. I have long wondered if the same thing happens to an ash cue shaft. Ash is more common in snooker than pool but I have never heard of a cue or cue shaft going flat. Even if it did, I don't know if that would be a bad or good thing. A cue is hitting end grain rather than side grain but I don't know how that affects cell structure.
I think quality carbon fiber shafts will come down to under three hundred dollars. When and if they do I think the writing will be on the wall for competition players, the end of the wooden shaft for practical purposes. They still have wooden racquet tennis matches, and some purists will play with wood as long as they play.
Your thread creates some interesting paths of thought. I don't really have any absolute answers. If I still had my cue shop I would build butts to look their best with carbon fiber shafts. I like wood but I hope nobody notices me turning my carbon fiber shaft trying to index a shaft that doesn't have a sweet side.
Thanks for starting a thread that causes some thought!
