Maybe I’m just lucky but I don’t think I have been. Instead, I just bought cues that were well made because I have never
had a cue shaft or cue butt I’ve owned, or presently have, warp. My Palmer cue is almost 60 years old and still straight as a taut string. My Runde Schon was completed in early 1985 and could pass for new and still perfectly straight. All of the ivory joint cues in my case are straight without wiggle or wobble and the newest cue in my case was completed over 10 yrs. ago.
If you deal with a quality cue maker, which I obviously must have based on how my pool cues have aged but remained
straight over the years, you shouldn’t have any problems unless you’re careless with how you carry & store your cues
I haven’t experienced any problems with warping or inlays/rings raising or any other issues. Buy quality and you will
not be disappointed, however, I suppose there is always the possibility it could happen with any cue maker. However,
my experience convinces me if the cue maker takes their time, the cue should turn out great. All of my custom cues, after being started, took 12-15 mths. to complete with every single cue maker I’ve used. Again, all my cues remain straight.
