I have an almost new custom that has about 1/32" lift in the shaft when rolled together, yet the shaft and butt roll dead straight apart. Can I please have some input on what would cause this? the cue has never been left in temperature extremes, and other than a couple of minor falls, it hasn't been abused at all. The cue was made for me and the cuemaker is going to check it out...I would just like some opinions.
