Cannon Break Cues has an ad in Inside Pool, that has an 800 number.
I don't know about other break cues, but the Cannon BC is a heavy cue (22-23 oz.)
I'm not a good source for comparisons between Break cues. I don't use them. Like I said, I have a soft break. I just make sure I hit the head ball as full as I can (playing 9 ball) , and I get good results from that.
One Pocket and 14.1 are my favorite games. No need for a hard break.
