I am about 95-99% sure, he means with the stock surface, the Dimension (and the Cell) are very even and early reacting balls with an arc-ing ball path. That is/was the definition for unpolished urethane balls. Polished, of course, they can be more resin-like, that is, more flippy reacting.
That is exactly what I found with my Cell. I am certain that was the reason the Dimension was designed.
Oh, unlike most urethane balls, these two have a lot of continuation at the backend, despite the early rolling type of reaction.
