Just a question to the Cue makers here, about low deflection Players shafts. I bought an HXT - 30 and liked the performance of the Cue. I wanted a back up shaft so I purchased one however, it is a different shaft insert. The HXT-30 came with a "piloted" Low Deflection shaft in 5/16 X 18. The spare shaft is the same but is flat at the insert. Is that going to be detrimental ? It threads on fine and seems to play fine. I don't mean to split hairs but, is a piloted insert there for a reason ? Should I return the shaft for piloted ?
