I have played with surface adjustments on my 2 - Cold Blood pieces... I actually kept one of them with a 1500 Abranet w/ FF polish on it and rolls pretty sweet. This ball has a pin up layout - 55 x 5 1/4 x 35 layout which was very rolly type of reaction for me... with the polish, it gets through the front part of the lane with a little more pop in the backends, but still a strong rolling piece. Use this ball a lot on the medium length patterns (38-41').... just gives me a strong rolling piece that is not too over/under on the backends.
Hope this helps your questions...
