Since you have the mid performance skid/flip reaction taken care of; this is the direction that I would go.

Heavy oil - UFO and Nuclear Cell
Mid Performance Smooth - IQ Tour Black and IQ Emerald
Mid Performance Angular - Phaze III and Idol Pearl
Mid Performance Benchmark - Axiom
Lower/Mid Performance - MVP Pearl
Light Oil - Tropical Surge

If you want to go urethane then the Pitch Purple.  But with you having medium revs; it may or may not match up with you as it seems the only guys making tv shows with urethane are those with rev rates over 400.  Technically you could conquer a wide variety of conditions with less balls but it is ultimately up to you.  If it was up to me, I would go this route.

Heavy - UFO
Benchmark - Axiom
Smooth - IQs
Angular - Either the Idol Pearl or Phaze III but not both.
Lower - Hustle HSB
Light - Tropical Surge

I just took you from 10 balls down to 7 but that did not include a urethane.
