Based on what you mention, I would go with the OMG. The solid cover on that ball is the strongest made by AMF (F84), being much stronger than your Double Clutch (F64). The OMG is known to give good midlane control with longer or heavier volume patterns and still provide good movement on the backend. Plus with a little slower ball speed with revs to match, it could become a really good piece in your bag.
The Critical Theory, Raw Profit, and OMG Pearl are all designed for medium-heavy conditions. The difference is all of those are stronger than your Double Clutch and Double Clutch Pearl.
The Shred-It would be a nice ball that would fill the gap between the OMG and the Double Clutch. The hybrid cover actually can help prevent over/under on the transition.
If you decide to revamp part of the arsenal, these would be my suggestions based on what you have and/or what you are deciding for a new ball. I also listed the ratings from AMF/900Global next to each.
Heavy oil: OMG (F84)
Medium-Heavy (transition): Shred-It (F74)
Medium-Heavy: OMG Pearl (F73), Raw Profit (S70), or Critical Theory
Medium: Double Clutch (F64)
Medium (wet/dry): Radar (F57) or Favorite (S57) - both are similar but like the Radar for wet/dry
Medium-Light: Double Clutch Pearl (F55)
Light: Roto Grip Mars
Hope this helps give a starting point for you.
