I recently bought a Prather SP to use as a break cue. My questions are: would it help any to use a phenolic ferrule instead of the standard ferrule that came on it, I believe it is an Ivorine type? Could the shaft receive unintended damage by adding this tip/ferrule combination? The shaft is 13mm and has a 3/8 x 1" joint with Phenolic collars. The brass(?) joint threads into wood in the shaft. Thank you in advance for your help. Pms with any expertise are much appreciated
