I see we have a problem here so I'll clear something up right now so we can get back on topic and the OP can get his answers....
THERE IS NO SUCH THING AS A HEAVY OIL BOWLING BALL!!!!
Bowling balls do not hook in the oil. Bowling balls require friction to hook and when oil is present there isn't friction so hook isn't happening.
Are there balls that have cores that make the ball change it's axis of rotation while it is in the oil? Yes there are.
Are there balls that change the axis of rotation of the ball faster than others? yes there are.
What makes a ball useful on a heavily oiled lane? The ball needs to change the axis of rotation from the bowler to an axis of rotation that matches up with the necessary entry angle at the pocket. In conjunction with the core changing the axis of the ball roll the coverstock must also be able to grip the lane.
Traditional dull resin and particle coverstocks gripped the lane with the traction generated from the sanding lines and the edges of the particles in the coverstock. The scratches and valleys between the particles in these balls allowed the ball to get into the lane (to borrow a NASCAR term) since the oil just filtered between the particles and through the scratches, much like the old Goodyear Aquatread commercials showed.
The new super-soft and tacky coverstocks and strong rolling cores (like the traditional Lane 1 Diamond core has historically been known for) lead to balls now that require less deep channels to get rid of the oil. Many smaller channels are doing the same job as a few bigger ones have done in the past.
You are attempting to compare apples to oranges to tangerines....all 3 are good for you but each has it's own benefit.
The coverstock on the Mission is not a pure pearl resin. The cover on the Curve is not a pure pearl resin. The C System balls are not pearl resins.
The stronger revving cores that Brunswick and Ebonite have put into the C systems and Missions are doing a better job at getting the rotational axis changed to the proper roll than they have in the past. The new coverstocks are just taking advantage of available friction down the lane better since the core has the ball set up to get into the pocket better.
If you oil the lane from foul line to the pins and throw identically drilled and prepped balls down the lane I doubt you will see much difference between any of these mentioned and a tropical storm.
Again...some balls have attributes that will enable them to work better than others on certain oil conditions for some people. However the ball that works great for bowler A on lane condition 1 may be a total flop for bowler B on the same condition.
There are no such thing as balls "made for oil" anymore....
