You're on heavier oil conditions, and you are thinking about using a pearl ball instead of a solid? That kind of defies logic. Pin under will mean the ball will begin its roll a little earlier and be more arcing, but it also reduces the response to friction which will cut back on entry angle. Pin down does not necessarily mean lots of early hook.
If the polished Attitude Shift is going too long, you should go with a strong, low RG rolly solid, like a Dimension or Cell, and keep the cover dulled. Your goal on heavier oil conditions is NOT to make the ball hook, but rather to generate more midlane reaction in an effort to get the ball to roll more for better carry and also be less reliant on friction. Use more of an up-the-back release to get the ball to tumble end over end more to create earlier roll, and play a more direct line with a strong ball with a solid coverstock to combat the heavier oil. (You may need to bring your breakpoint closer to the headpin to achieve the correct entry angle, it all depends on how long the oil pattern actually is) Then as the heads start to dry up, you can start moving in and swinging it out more, throw a ball that gets through the heads cleaner, or both. Your polished Attitude Shift may be a good fit for this, unless the carrydown gets too heavy for the ball to react consistently. You may want to leave it at 2000 or 4000 abralon to combat that.
