What you are describing is what I see from pearl surfaced bowling balls. Because most (not all) have slip agents in the surface versus solids that do not, the ball gets better length than a solid even if you put the surface of a solid and a pearl of the same ball at the same surface (think sanding down an original Optimus versus the Optimus solid). The pearl cover and slip agents for me causes the ball to slide on any amount of oil, but once it sniffs dry, flips and turns to the point it is almost overreaction, thus what I consider an over-under reaction.
I have the Optimus solid and love the reaction. Everyone is different but you might as well.
