I had one drilled one up last week. 4x4x1 layout. I buy a decent amount of equipment and I've had some balls I've really liked, but this ball matches my game perfectly. Used it thursday and had 490 after 2 before having to put it away. Used it in a big local tournament on saturday and led my bracket through 3, shooting 778 scratch. Unfortunately my shot, and body, didn't hold up and I was not able to hold the lead. Bowled league that night (after 8 games in the tournament) and shot 737. My league averages fall between 205 and 211 currently.
I really liked the Storm balls I threw last year, but decided to try some other stuff when I dropped to 14lbs. While some of those balls have been very good, I can't believe how well this ball works for me. Convinced me to try some more Roto Grip balls. The Daredevil is in the shop waiting to be drilled up. Hopefully getting it tonight.
In terms of ball motion, this ball allows me to play my A game (outside 10 - straight up to swinging the ditch) with some decent speed. Gets some decent length and comes off the spot with good continuation. Not as skid/flip as the Code Black that I have, and drives the pins better. I like that Code Black as well, but the NRP is something else. I'd say this ball is a combination of the Fix (motion hole layout) and the Code Black - my 2 previous purchases before this, but with more continuation. Handles the oil better than either of those balls as well, and does not soak it up as much as the Fix.
