Question: What is mass bias and which balls have it?
A: Mass bias is the extra lopsided weight inside asymmetrical cores that creates an additional preferred spin axis. It gives the ball more torque and aggressive angularity on the backend. Only asymmetrical cores have significant mass bias. Higher mass bias equals more snap and is why asymmetrical balls dominate on tough sport patterns and heavy oil.
