I believe it's all about having that right cover/core combination. You can have that same ball with another core, and it will defnitely react different.
You're asking how the cell pearl still has all that backend with that "rolly" core. Well sir bowl and backinthegame are defintely right. The pearlization process gives that ball the length, which saves energy going down the lane. When it comes out of the pattern, all that energy is unleashed. That strength comes from the cover/core combination.
