Have you ever sliced butter? That's what this ball does to oil: it cuts right through the oil, finds any tiny bit of friction it can, and starts to move. Mine is drilled stacked leverage for a full roller, and I have to give it a LOT of angle through the front to keep it right of the 1-3 (probably more than normal because I'm a lower speed player). This thing will also beat up the heads like no tomorrow. I don't usually find myself moving more than once in a 6 game practice session with anything I throw, but if I repeat the exact same shot with this ball I'm moving every 4-5 frames or less. It's pretty intense.
Needless to say most bowlers will never find a house shot to use this on. I use it in the most flooded house I know and I still end up lofting to get it to push far enough right. However, at a competition with a sea of oil, this ball gives me complete confidence that no one has the look I have (and as they move left they're moving into burnt up heads tehehe). Just push it far enough right and let it plow through the pins.
