I don't know that I would call it a true "heavy" oil ball. I would say it is best suited for medium to medium-heavy shots that have plenty of head oil. Surely it can handle heavy oil as well, but there are likely better options, such as the Maxxx Curve. It is one heck of a ball though. It's very smooth off the breakpoint, but still packs a nice punch on the backend. A great blend of power and control.

Droid Pearl is a really good ball too, though it won't handle as much oil as the solid Droid. It is super clean through the front of the lane, then responds quickly to friction for a angular move on the backend. I would say the Droid pearl is a good medium choice, Droid solid is a good medium-heavy ball. I don't know much about the Epidemic, have yet to see one thrown.
