The AMB Particle will handle the most oil. Even on the heaviest soup, I can only get it to the arrows before it starts rolling. After about 20 games, the hook diminishes, but the ball just continues to roll. Becomes more predictable.
Granite Gargoyle has the same cover, but doesn't roll quite as early, but is a very consistent ball.
The Frankie May is an early rolling reactive that can handle a bunch of oil, but polished, can handle lighter sides of medium. The Low RG core gets the ball revved up, and provides a strong arc on the backend.
The Immortal Solid has the same cover as the Frankie May, but with a MUCH stronger weightblock. Will cover more boards than all previously mentioned balls, but will cover them mainly on the backend. Can be over-under, and if drilled too strong, will over flare. With the correct drilling and surface, I think this would be the ball.
AMB Solid would also be a strong choice, if sanded up more than box finish. Slightly weaker weightblock than the Immortal, with the same cover as the Frankie May. Not as over-under as the Immortal.
