I have not thrown both, I have the Bank Pearl and have seen Break Point Pearl.....Bank Pearl is smoother from what I have seen and possibly a bit stronger overall.....I have always had major over/under issues with strong pearl balls, the Bank Pearl is by far the best strong pearl Ive ever thrown. It will slide a bit in heavier fresh oil and slick conditions, but thats not really what the ball is meant for....IMHO. I use it for med/med heavy conditions....I think its a great piece and compliments my Track "T" series balls well
