I resaw a lot of boards for various purposes - veneer, laminated bent work, book matched parts, etc.
The most stable boards i ever saw tend to be air dried for a "long time".
Fresh kiln dried is about the worst. Too much stress in it, even if the people running the kilns know, care, and run stress relief cycle.
After KD wood sets in the loft of my humidity controlled shop for (it seems to me) about 7 years, it evens out to be about as stable as air dried.
Kiln drying can partially set the sugars, depending on temp, but regular KD is not equal to torrifying.
Another very good thing with KD and especially maple, is it kills the worms. It is devastatingly easy for hard maple, and holly, to go all wormy if you let your shop humidity get up too much, and if the wood was not KD. Storing wood like that in a regular barn for long is an invitation for worms. Unless it is way up high in the loft and never gets damp air for extended periods.
Cuemakers & perhaps all us woodworkers have a lot of superstitions that work, but not always for the reasons we think they do.
