"There's more than one way to skin a cat" ......who comes up with these sayings?
I was of the mindset that you should play pool with one cue for that reason also, this particular question depends on how you break also a) for control b) for maximum dispersion. If you're breaking 60-70% like SVB and you use a hard tip then you won't have issues with your tip losing it's perfect shape, also he has quite a few shafts in his case to choose from if something goes wrong and his tip flies off, damages his ferrule, etc. etc.
We don't have the same situation as one person, who is sponsored by a cue manufacturer, that has one of the most efficient breaks on the planet (if not THEE most efficient break) we are normal players with a normal number of shafts and need help maximizing the break shot.......at least I do.
When breaking for control I use my playing cue since I like hard tips since I'm a banger, love the Saga tips from Seyberts for many reasons. So in essence the answer to his question depends on what the intention of the break is in the first place, what if he was talking about one pockets breaks ha ha.
