Here's the deal. I have a Predator BK (hard sumo leather tipped) break cue that I use to break with during my league matches, that are played on 9 foot tables, where the cue balls are the same size as all the other balls. But when I play on coin operated 7 foot, bar room tables, that have those BIGGER and HEAVIER balls, I use my phenolic tip cue to break with. My thinking is the phenolic break cue will give me a better break against those BIGGER BALLS and I don't have to worry about wearing out the tip on my predator break cue. Is that true?
