background.....Historically, I used a cue the same or slightly lighter than my playing cue which is a 19.
Then I had a heavy breaker made for me at about 25 and it was shorter and thicker than my player, hit like a ton.
Then a fellow player, who is also a golfer, said this is all wrong, your breaker should be lighter to get more velo on the cue ball for harder breaks.
Then I saw some videos on YouTube where the guy said, and proved, that he got a stronger hit, more speed with a heavy cue.
So bottom line is that I have used both light cues, 18 and heavy 25 and really can't see much difference in results but think I prefer a heavy cue for my style, age, ability....so maybe that's the answer right there?? Who knows? I rarely get a shot after the break anyway.
I'll go back to my corner and shut up now.
