Thanks for the stats- that does give a good starting point.
I would probably go with a surface change first to see if it may still be usable. OOB on the Omen is prepped at 500/500/4000/4000. Maybe a change to 800/1000/2000/4000 without polish (used on the Ebonite Vital Energy) could work. The VE is similar to the Omen in that both balls handle medium-heavy oil and use similar pearl covers. Using that finish would give the ball some extra teeth and should allow you to pick up the midlane slightly earlier.
If that doesn't work, I would try 500/1500 with polish as was done on the Storm Anarchy. That should give you more midlane read with a continual arc/heavy roll in the backend. Either of those surfaces should work better for some longer patterns with medium-heavy oil.
If a surface change doesn't work, then maybe changing the layout and pin position could benefit you.
My Arsenal (as of February 2012)
Heavy Oil: Roto Grip Defiant: 3000 AB
Medium-Heavy Oil: Track 919C: 3000 AB
Medium-Heavy Oil: Ebonite Vital Energy: 4000 AB
Medium Oil: Track 505T: 4000 AB
Medium-Light Oil: Hammer Brick: 2000 polished
