I'd have to agree with the Rule Delta 1 being VERY versatile in terms on coverstock adjustments. I've used a burgundy pad (approx.320-400 grit) all the way to 2000-grit wetsand with A LOT of polish (shiny as a marble).
At 400-grit, the ball is sooooo extremely aggressive. It doesn't quite get passed the heads. Most of the time, it's in the left gutter at 20-30ft. if the volume of oil isn't high enough. With anything less than 800-grit, I really have to play deep and keep the ball in the oil, and I can even play the out of bounds area.
Highly polished, this ball saves so much energy and makes quite an angular and strong move on the backend. It's still not as skid/flip as the Xception though. I can still play deep, but just like most highly polished balls, it will skid past the breakpoint if it's in the oil too long. With this surface, I can play multiple parts of the lane.
At whatever surface I've tried, the ball enters the pin deck so well. I think I have left more 9-pins with the Rule Delta 1 than any other ball I've had.
