Regardless of what the cue is, if you like it and want hang on to it a while
you should know that there is an option that prevents this issue from recurring.
Have the jnt converted to 3/8x10.
Since you're already getting a new shaft, have a 10-pin installed in the handle/butt
and you'll never be lost for a shaft again. I'd replace the jnt collar as well.
