Want to try a Players HXT shaft, however, my two main playing cues use a 5/16x18 piloted joint, and everyone seems to be sold out of those. I looked at the Pure X playing cues, and they use a 5/16x18 flat faced joint. If I bought one of the cues, would the flat faced shaft work on a looted joint, or would there be problems? I figured that way, I'd have the shaft, plus the extra cue butt.
