I have some shaft blanks and was curious to whom you would recommend into making shafts that would fit a Schon..........So who would you recommend to make a shaft?
Answer one is, whatever cue maker makes the cues you most like the hit of is who you should have make the shafts (since the majority of the way the cue plays/hits comes from the shaft anyway).
Answer two is, if you know whose cues you most like the hit of, but the problem is that they are either retired or deceased, then start a new thread on here asking what cue makers have a hit and play that is closest to the X cue maker that you prefer, or who has all the specs of the shafts of cue maker X and can replicate their shafts.
Answer three is, if you don't have enough experience to know whose cues you most like the hit of, then just pick anyone, doesn't much matter who, because it is just going to be a total shot in the dark as to whether you end up liking it or not anyway, and that includes even if we help you pick it (which is probably even a bigger shot in the dark). You should also probably start trying out other people's cues whenever you can so you can learn exactly what you like in the way a cue hits and plays, and who it is that makes that type of hit, that way you will never have to wonder what maker/s to buy again.
Answer four is, especially if you don't know what type of hit you most like and who makes it, is to just go with whoever it was that made the butt, in this case Schon. That way you keep the cue original to one maker which is a bit more appealing if you should ever want to sell it down the road.
With only the limited information you have provided so far, it seems like having Schon make the shafts is probably the no brainer here. You already know you like the Schon hit at least a good part of the time for most of their shafts you have tried, so your odds for liking a new shaft from them is probably way better than your odds for liking some random shot in the dark you take based on our suggestions, plus the maker will be the same for whole cue which is usually a bit more desirable/easier to sell if ever needed.
