I have not seen these two balls side to side. Overall, the World Beater would be strong because the larger core would dictate early roll and be heavier rolling.
The total bedlam has a slimmer core which would dictate more length, but the strong cover will allow it to cover more boards quickly.
I'm in the process of trying to find out where I fit in the bowling world. I do not know my tech specs of my game, but it's all a learning process.
