I have done a lot of repairs through the years and have seen very few perfectly straight shafts, no matter where they came from. Rolling a cue on the table while in a standing position may allow a cue to look perfectly straight, but that does not mean something has not warped a little. Around ten years ago when the cues from the Philippines started flooding the USA market, overall they were some of the most unstable cues I had seen. But many cuemakers from over there have improved their methods and started producing some more stable cues in recent years.
As a general rule butts are more stable than shafts and do not get the same bending and such that shafts get and are more prone to staying straight. Wood is wood no matter who is working with it and rushing the process will produce more warpage. Coring has cut down on butt warpage and pie shaped laminating and other lamminating methods cuts down on shaft warpage. But I have seen laminated shafts that are not perfectly straight also. I have seen a lot of the "perfectly straight" term being used in this thread. Perfect is a word I have rarely seen to accurately describe the straightness of any used shaft with any age on it. Pretty straight is more accurate in my experience. Some using the Perfect word here might be surprised if they had a cuemaker put the cue between centers on their lathe and get an indicator reading on the run out.
