Some very good oil balls are Brunswick's (recently "deceased") Fuze Eliminator and the new Impulse Zone. Both are light load particles, the Impulse Zone being the overall more aggressive and modern ball.
If you can give them revs, they both will be very good oil choices which offer lots of grip, yet are able to get down the lane even when the heads run dry and the lane is spotty. Not good for bone dry backends, except for the case that you get them down with speed, but nevertheless offering control and stable reactions.
