Sounds like a pretty strong assortment. The only things missing (as far as I can tell) are a ball for the dry (although the Power Groove will do) and for deep oil.
The Goliath is quite special, since it is a high load particle which can get endangered to burn out on short patterns. Maybe you should ask a local pro for help.
The Impulse Zone should be a good oil ball with an according, earlier drilling than the Zone Classic. It seems to have a lot of traction.
An Ultimate Inferno would also be a good choice for a strong, early rolling reactive ball on heavy oil.
But besides that, your arsenal sounds quite complete?
