Best pool cue break sticks available ?

Any quality cue can be used for a "break stick". It needs to be made of hard rock maple with a quality ferrule and the weight is your decision. Most people think that a heavy cue (21 or more ounces) is best for breaking. Most pro players use a light, one-piece cue (18 to 20 ounces) for this purpose. It's cue velocity, not mass, that produces the highest release of energy at impact. A hard tip is necessary to create the highest speed at cue and cue ball impact. Lately everyone is useing the synthetic tips for break cues. Practice, practice, practice!
